What Is the Bighorn Medicine Wheel?/info

Introduction

The Bighorn Medicine Wheel is a stone construction situated at approximately 2,939 metres (9,642 feet) elevation on Medicine Mountain in the Bighorn Range of north-central Wyoming. Comprising a roughly circular alignment of limestone boulders approximately 24 metres in diameter, with 28 radiating spokes connecting a central cairn to the rim, and six smaller peripheral cairns, the structure represents one of the largest and most architecturally complex medicine wheels on the Northern Plains. Its high-altitude placement renders it accessible only during the brief summer months, a constraint that has shaped both its use history and the seasonal character of the astronomical alignments attributed to it.

The site was designated a National Historic Landmark in 1970 and has been the subject of sustained archaeological, archaeoastronomical, and ethnohistorical investigation since the mid-twentieth century. Archaeological evidence from the broader Medicine Mountain landscape indicates human visitation spanning approximately 7,000 years, though the wheel structure itself appears to be considerably younger — likely constructed and modified over several centuries within the last millennium. The Bighorn Medicine Wheel holds ongoing ceremonial significance for multiple Indigenous nations, including the Crow, Cheyenne, Arapaho, Shoshone, and Lakota peoples.

Research attention has been concentrated on two principal questions: the astronomical functionality of the cairn-to-cairn alignments, and the ethnographic identity of the builders and their ritual purposes. These lines of inquiry have produced competing but not necessarily incompatible interpretations, ranging from a high-altitude solar and stellar observatory to a Cheyenne medicine lodge analogue to a vision quest site serving multiple tribal traditions.

What we know

The Bighorn Medicine Wheel consists of a central cairn approximately 3.7 metres in diameter, from which 28 stone spokes radiate outward to a roughly circular rim. Six additional cairns are positioned on or near the rim at irregular intervals, designated in the archaeological literature as cairns A through F (with O representing the central cairn). The entire structure is built from locally sourced limestone boulders and sits on a relatively flat, exposed ridge.

The earliest systematic archaeological investigation was conducted by the Wyoming Archaeological Society under Don Grey in 1958, published in summary form in 1963. Grey's excavation of the cairns yielded limited cultural material: a piece of wood lodged in cairn F produced a radiocarbon date corresponding to approximately the mid-eighteenth century CE, though this represents a minimum age, as the wood may have been deposited after initial construction. No diagnostic artifacts were recovered from the cairns themselves, and Grey concluded that the structure's primary function was ceremonial rather than domestic.

In 1974, solar physicist John A. Eddy published a landmark analysis in Science demonstrating that specific cairn pairs produced sight lines aligned with the summer solstice sunrise and sunset: cairns E-to-O marked solstice sunrise, and cairns C-to-O marked solstice sunset. Eddy further identified three additional cairn pairs whose sight lines corresponded to the heliacal rising points of the bright stars Aldebaran (in Taurus), Rigel (in Orion), and Sirius (in Canis Major) — stars whose first pre-dawn appearances in the summer months could have served as calendrical markers for solstice prediction.

Jack Robinson subsequently identified a fourth stellar alignment, involving cairn D and the star Fomalhaut, whose heliacal rising preceded the summer solstice by approximately 28 days. This added a potential pre-solstice warning signal to the calendrical scheme. Robinson's 1980 study also confirmed parallel alignments at the Moose Mountain Medicine Wheel in Saskatchewan, suggesting a shared astronomical tradition across a wide geographic area.

Bradley Schaefer's 1986 reanalysis introduced important methodological caution. Schaefer demonstrated that atmospheric extinction — the dimming of starlight near the horizon — had not been adequately accounted for in earlier alignment studies, and that the visibility of stars at the claimed rising azimuths depended critically on atmospheric conditions at the specific altitude and latitude of each site. His work raised the statistical bar for confirming or refuting stellar alignments, though it did not definitively invalidate Eddy's solstice alignments, which depend on solar rather than stellar observations.

Anthropologist Karl Schlesier proposed an alternative interpretation grounded in Cheyenne ethnohistory. Schlesier argued that the 28 spokes correspond to the 28 poles of the Cheyenne medicine lodge (a precursor to the sun dance lodge), and that the wheel's stellar alignments are consistent with Cheyenne ritual practices. He suggested the Bighorn wheel and the Moose Mountain wheel represent tribal boundary markers and ceremonial structures associated with Cheyenne cosmological traditions.

The broader landscape of Medicine Mountain contains extensive additional archaeological evidence: tipi rings, lithic scatters, wood-gathering areas, and other stone features. The U.S. Forest Service has documented visitation and use by at least seven distinct tribal nations. Contemporary Indigenous communities continue to use the site for prayer, offerings, and ceremony, and the management of the site involves ongoing consultation between federal agencies and tribal representatives.

The 28 spokes have invited multiple interpretations beyond Schlesier's medicine lodge hypothesis. The number corresponds to the approximate length of a lunar month, and some researchers have proposed a lunar calendrical function. However, no definitive evidence links the spoke count to any single calendrical system, and the number 28 carries significance in multiple Indigenous cosmological traditions.

Classification of theories

A. Plausible explanations (supported by evidence, not refuted):

1. Solar observatory / solstice marker. Eddy's solstice alignments (cairns E-O for sunrise, C-O for sunset) remain the most robust astronomical claims. Solar alignments do not suffer from the atmospheric extinction issues that complicate stellar claims. The site's accessibility only during summer months is consistent with solstice-focused use.

1. Multi-tribal ceremonial and vision quest site. Extensive ethnohistorical evidence supports use by multiple Indigenous nations for ceremonial purposes including vision quests, prayer, and offerings. The broader Medicine Mountain landscape shows 7,000 years of visitation.

1. Cheyenne medicine lodge analogue. Schlesier's interpretation, linking the 28 spokes to the Cheyenne medicine lodge structure, is supported by ethnohistorical parallels, though it cannot account for why other tribal nations also claim historical connections to the site.

B. Possible explanations (raised by researchers, less well supported):

1. Stellar observatory for heliacal rising events. Eddy's stellar alignments (Aldebaran, Rigel, Sirius) and Robinson's Fomalhaut alignment are plausible but methodologically contested following Schaefer's atmospheric extinction critique. They remain possible but not confirmed.

1. Lunar calendar. The 28-spoke count suggests lunar reckoning, but this interpretation lacks independent corroborating evidence beyond the numerical correspondence.

1. Tribal boundary marker. Schlesier proposed this function alongside the ceremonial interpretation; it remains possible but difficult to test archaeologically.

C. Highly unlikely but argued by some:

1. Single-culture, single-purpose construction. The archaeological and ethnohistorical evidence strongly favours a composite structure built, modified, and used by multiple groups over centuries. Monocausal explanations are inconsistent with the site's complexity.

Landmark Studies

1. Eddy, John A. "Astronomical Alignment of the Big Horn Medicine Wheel." Science, vol. 184, no. 4141, 1974, pp. 1035–1043. DOI: 10.1126/science.184.4141.1035 Full text: https://www.science.org/doi/10.1126/science.184.4141.1035 [publisher paywall] Alternative: https://sherrytowers.com/big_horn_medicine_wheel.pdf [open access — hosted copy]

[Publisher abstract] The Big Horn Medicine Wheel, a pattern of stones on a high plateau in Wyoming, may have been an astronomical observatory used by prehistoric Indians. Cairn-to-cairn sight lines mark the places of rising and setting of the Sun at summer solstice; additional sight lines appear to mark the rising places of the stars Aldebaran, Rigel, and Sirius at a date consistent with construction two to four centuries ago.

Full-text notes: Eddy's paper established the field of Plains archaeoastronomy. His methodology involved surveying all possible sight lines between the central cairn and the six peripheral cairns, then testing each against the azimuths of solar and stellar events. Of the 21 possible cairn pairs, he identified five with convincing astronomical correlations. The solstice alignments proved most robust, with sunrise and sunset lines accurate to within one degree.

The stellar identifications depended on calculating the heliacal rising azimuths for bright stars at the site's latitude and altitude, and then accounting for precession to determine when the alignments would have been most accurate. Eddy estimated a construction date of approximately 1400–1700 CE based on the precession-corrected best fit of the stellar alignments. This date range proved broadly consistent with Grey's radiocarbon date from cairn F.

Eddy was careful to note the limitations of his analysis: the crude construction of the cairns introduces azimuthal uncertainty of approximately one degree, and the statistical significance of any alignment claim depends on how many candidate alignments are tested. Nonetheless, the convergence of multiple alignments with astronomically significant events at a consistent epoch was, in his assessment, unlikely to be coincidental. The paper's influence extended well beyond the Bighorn site, stimulating a generation of alignment studies at medicine wheels and other Indigenous stone constructions across the Northern Plains.

2. Grey, Don. "The Big Horn Medicine Wheel Site, 48BH302." Plains Anthropologist, vol. 8, no. 19, 1963, pp. 27–40. DOI: 10.1080/2052546.1963.11908211 Full text: https://www.jstor.org/stable/25666476 [publisher paywall]

[Agent-generated summary] Grey's report presents the results of the 1958 Wyoming Archaeological Society excavation of the Bighorn Medicine Wheel, the first systematic archaeological investigation of the site. The excavation focused on the central and peripheral cairns, documenting their construction methods and recovering limited cultural material.

Full-text notes: Grey's excavation established the foundational archaeological record for the site. The cairns were found to be deliberately constructed from locally collected limestone boulders, with the central cairn being the most substantial. The only datable material — a wood fragment from cairn F — produced a radiocarbon result consistent with the mid-eighteenth century CE, providing a terminus ante quem but not a construction date.

Grey documented the absence of diagnostic artifacts within the cairns themselves, noting that culturally modified materials were found in the surrounding landscape but not in direct association with the wheel structure. This negative evidence contributed to the interpretation that the wheel served a ceremonial rather than a habitation or utilitarian function. The report remains the primary source for the physical archaeology of the wheel proper, as subsequent investigations have focused on the broader Medicine Mountain landscape rather than re-excavating the monument itself.

3. Robinson, Jack H. "Fomalhaut and Cairn D at the Big Horn and Moose Mountain Medicine Wheels." Archaeoastronomy, vol. 3, 1980, pp. 15–19. Full text: https://www.proquest.com/openview/e41d2b7453a6462c2cae9b5dd9cf904d/1 [link unverified — may require institutional access]

[Agent-generated summary] Robinson extended Eddy's alignment analysis by identifying a fourth stellar sight line at the Bighorn Medicine Wheel, involving cairn D and the star Fomalhaut, and confirmed parallel alignments at the Moose Mountain Medicine Wheel in Saskatchewan.

Full-text notes: Robinson's identification of Fomalhaut as a fourth stellar target strengthened the astronomical interpretation by adding a pre-solstice warning marker approximately 28 days before the summer solstice. The parallel finding at Moose Mountain — a structurally similar medicine wheel approximately 600 kilometres to the north in Saskatchewan — suggested a shared astronomical tradition rather than a site-specific phenomenon.

The cross-site comparison was methodologically significant because it provided an independent test of the alignment hypothesis: if the same stellar targets appeared at two structurally similar but geographically distant sites, the probability of coincidence was substantially reduced. However, Schaefer's later atmospheric extinction critique applied to Robinson's stellar claims as well as to Eddy's, leaving the Fomalhaut identification in a state of plausible but unconfirmed status.

4. Schaefer, Bradley E. "Atmospheric Extinction Effects on Stellar Alignments." Archaeoastronomy, vol. 10 (Supplement to the Journal for the History of Astronomy, vol. 17), 1986, pp. S32–S42. DOI: 10.1177/002182868601701003 Full text: https://journals.sagepub.com/doi/10.1177/002182868601701003 [publisher paywall]

[Agent-generated summary] Schaefer's paper introduced a rigorous atmospheric extinction model to the evaluation of claimed stellar alignments at archaeological sites, demonstrating that many previously proposed alignments were compromised by the failure to account for the dimming of starlight near the horizon.

Full-text notes: Schaefer's contribution was primarily methodological rather than site-specific. He demonstrated that a star's heliacal rising azimuth depends not only on its celestial position and the observer's latitude, but critically on the atmospheric extinction coefficient at the observation site — which varies with altitude, humidity, and aerosol content. At the high altitude of the Bighorn Medicine Wheel, extinction is reduced, making stellar observations more feasible than at lower-elevation sites, but Schaefer showed that previous analyses had not adequately modelled these effects.

The paper did not reject the Bighorn alignments outright, but raised the evidentiary threshold considerably. Schaefer's framework became the standard against which subsequent stellar alignment claims were evaluated in archaeoastronomy. The solar alignments identified by Eddy, which do not depend on near-horizon stellar visibility, remained unaffected by Schaefer's critique. The paper thus sharpened the distinction between the well-supported solstice alignments and the more speculative stellar alignments at medicine wheel sites.

5. Schlesier, Karl H. "Rethinking the Midewiwin and the Plains Ceremonial Called the Sun Dance." Plains Anthropologist, vol. 35, no. 127, 1990, pp. 1–27. DOI: 10.1080/2052546.1990.11909530 Full text: https://www.jstor.org/stable/25669212 [publisher paywall]

[Agent-generated summary] Schlesier's ethnohistorical analysis reinterprets the Bighorn Medicine Wheel and related structures as Cheyenne ceremonial constructions linked to medicine lodge traditions that predate the historically documented Sun Dance ceremony, connecting the 28-spoke structure to the 28-pole lodge framework.

Full-text notes: Schlesier drew on extensive ethnohistorical research to propose that the Bighorn Medicine Wheel represents a form of Cheyenne ceremonial architecture with deep antiquity. His key insight was the structural homology between the 28 spokes of the wheel and the 28 poles of the Cheyenne medicine lodge, which he argued represent a pre-contact ritual tradition ancestral to the Sun Dance as documented in the ethnographic record.

This interpretation shifted the explanatory emphasis from astronomy to ethnography, proposing that the alignments identified by Eddy and Robinson were secondary to the structure's ritual architectural significance. Schlesier also proposed that such wheels served as territorial markers, formalizing the boundaries between tribal ranges on the Plains. His work has been influential in Indigenous studies, though some archaeologists have noted that it does not explain why multiple non-Cheyenne nations also claim historical connections to the Bighorn site.

6. Brumley, John H. Medicine Wheels on the Northern Plains: A Summary and Appraisal. Archaeological Survey of Alberta, Manuscript Series No. 12, 1988. Full text: https://archive.org/stream/medicinewheelson00brum/medicinewheelson00brum_djvu.txt [open access — Internet Archive]

[Agent-generated summary] Brumley's monograph provides the most comprehensive archaeological survey and typological classification of medicine wheels across the Northern Plains, establishing a formal definition and morphological taxonomy that remains the standard reference for the site type.

Full-text notes: Brumley defined the medicine wheel as a stone construction possessing at least two of three diagnostic traits: a central cairn, one or more concentric stone circles, and two or more radiating stone lines. This definition identified approximately 70 confirmed medicine wheels across the Northern Plains at the time of publication, with the Bighorn wheel being among the most complex morphologically.

Brumley's classification distinguished several subtypes based on the presence or absence of spokes, peripheral cairns, and ring structures, and attempted to correlate morphological types with chronological periods and functional interpretations. He drew on ethnographic accounts from Blackfoot and other Plains nations to connect certain wheel forms with memorial practices for warrior chiefs. The monograph remains essential for placing the Bighorn wheel in its broader cultural and geographic context, demonstrating that it is one manifestation of a widespread Plains tradition with considerable regional variation.

Recent Studies

[Agent-generated summary] Brace's volume documents the extensive corpus of boulder constructions in Saskatchewan, including medicine wheels, effigy figures, and cairn alignments, providing updated survey data and reassessing astronomical alignment claims in the Canadian context.

Full-text notes: Brace's work is valuable for its systematic documentation of medicine wheel sites in Saskatchewan, many of which had not been formally surveyed. His treatment of the Moose Mountain Medicine Wheel — the key comparative site for the Bighorn wheel — included updated measurements and a reassessment of Robinson's alignment claims. Brace adopted a cautiously supportive stance toward solar alignments while noting the ongoing methodological difficulties with stellar claims, consistent with the post-Schaefer consensus.

The volume also documented the variety of non-wheel boulder constructions on the Plains, providing context for understanding medicine wheels as part of a broader tradition of stone monument building rather than as isolated anomalies. This comparative perspective has influenced more recent researchers to consider medicine wheels within the full repertoire of Indigenous landscape modification.

8. Sundstrom, Linea. "Mirror of Heaven: Cross-Cultural Transference of the Sacred Geography of the Black Hills." World Archaeology, vol. 28, no. 2, 1996, pp. 177–189. DOI: 10.1080/00438243.1996.9980340 Full text: https://www.jstor.org/stable/124893 [publisher paywall]

[Agent-generated summary] Sundstrom examines sacred geography in the Black Hills and Northern Plains region, including the role of medicine wheels in Indigenous cosmological mapping, arguing that these sites encode spatial relationships between earth and sky that were transmitted across cultural boundaries.

Full-text notes: Sundstrom's analysis placed the Bighorn Medicine Wheel within a broader framework of Indigenous sacred geography, arguing that the site cannot be understood in isolation from the network of sacred places across the Northern Plains and Rocky Mountain regions. Her concept of "mirror of heaven" — the idea that terrestrial sacred sites encode celestial patterns — provided theoretical grounding for the astronomical interpretation while embedding it in a richly ethnographic context.

The paper is notable for its treatment of cross-cultural transmission, addressing the question of how the same site could hold significance for multiple tribal nations with distinct cosmological traditions. Sundstrom proposed that certain landscape features became shared sacred geography through processes of cultural contact and exchange, rather than being exclusive to any single group.

9. Oetelaar, Gerald A. "Implicit Assumptions and the Writing of Plains Prehistory." Plains Anthropologist, vol. 59, no. 231, 2014, pp. 250–268. DOI: 10.1179/0032024014Z.00000000025 Full text: https://www.tandfonline.com/doi/abs/10.1179/0032024014Z.00000000025 [publisher paywall]

[Agent-generated summary] Oetelaar critiques implicit assumptions in Plains archaeology, including the treatment of medicine wheels and other stone constructions, arguing that archaeological interpretations have been constrained by Eurocentric frameworks that fail to engage meaningfully with Indigenous knowledge systems.

Full-text notes: Oetelaar's paper is significant for the Bighorn Medicine Wheel discussion because it challenges the analytical frameworks that have dominated academic study of the site. He argued that the dichotomy between "astronomical observatory" and "ceremonial site" is itself a product of Western analytical categories, and that Indigenous knowledge systems integrate astronomical, spiritual, and practical functions in ways that do not map neatly onto disciplinary boundaries.

This critique has influenced recent collaborative approaches to medicine wheel research, in which tribal representatives participate as knowledge holders rather than merely as informants. The paper reflects a broader shift in Plains archaeology toward greater epistemological pluralism and respect for Indigenous intellectual traditions.

[Agent-generated summary] A recent popular-academic treatment of the Bighorn Medicine Wheel that summarises current understanding of the site's archaeology, astronomical alignments, and ongoing Indigenous ceremonial use, reflecting the contemporary consensus that the structure served multiple, overlapping purposes.

Full-text notes: This 2025 article provides a useful overview of the current state of knowledge, noting the U.S. Forest Service's documentation of 7,000 years of visitation on Medicine Mountain and the composite construction history of the wheel itself. The piece reflects the growing consensus that the astronomical, ceremonial, and territorial interpretations are complementary rather than competing, and that the site's significance resides precisely in its multi-dimensional character.

Future Research Directions

High-resolution remote sensing technologies — including LiDAR, drone-based photogrammetry, and multispectral imaging — offer the potential to document the Bighorn Medicine Wheel and its surrounding landscape at unprecedented spatial resolution without disturbing the site. Such surveys could reveal construction sequences, identify previously undetected stone features, and provide precise three-dimensional data for alignment analysis that surpasses the accuracy of earlier ground-based surveys.

Optically stimulated luminescence (OSL) dating of sediments trapped beneath and between the stones could provide independent chronological constraints on the construction and modification history of the wheel. This technique, which dates the last exposure of mineral grains to sunlight, has been successfully applied to other stone constructions and could resolve the long-standing uncertainty about whether the central cairn predates the spoke-and-rim complex.

Ethnographic and oral historical research conducted in genuine partnership with the tribal nations who maintain ceremonial connections to the site remains the most promising avenue for understanding its cultural significance. Indigenous knowledge holders possess transmissions about the site's purposes, protocols, and history that have not been fully integrated into the published archaeological literature, in part due to the sensitivity and restricted character of some ceremonial knowledge.

Comparative archaeoastronomical studies using modern atmospheric modelling software could revisit the stellar alignment claims with the rigour demanded by Schaefer's critique, specifically modelling atmospheric extinction at the precise altitude, latitude, and likely historical atmospheric conditions of Medicine Mountain. Such analyses could either confirm or definitively refute the stellar alignment hypothesis with a degree of certainty that has not yet been achieved.

Summary of Existing Research and Public Opinion

The Bighorn Medicine Wheel has been the subject of sustained academic attention since the 1950s, with two principal interpretive traditions emerging: the archaeoastronomical approach inaugurated by Eddy (1974) and the ethnohistorical approach advanced by Schlesier (1990). These traditions are not mutually exclusive, and the emerging consensus treats the site as a multi-functional sacred landscape whose astronomical, ceremonial, and territorial dimensions are complementary.

The solar alignments identified by Eddy — particularly the solstice sunrise and sunset sight lines — are generally accepted as genuine, though the stellar alignments remain contested following Schaefer's methodological critique. The archaeological record, while limited by the constraints of excavating a protected sacred site, supports a composite construction history spanning several centuries.

Public awareness of the Bighorn Medicine Wheel has grown significantly since its designation as a National Historic Landmark, and the site attracts both academic visitors and spiritual practitioners. The management of the site has become a case study in the negotiation between scientific access, public education, and Indigenous ceremonial rights. The U.S. Forest Service's collaborative management approach, involving consultation with tribal representatives, is widely regarded as a positive model for the stewardship of sacred sites on public lands.

Among the general public, the astronomical interpretation tends to dominate popular accounts, with the site frequently described as "America's Stonehenge" — a comparison that, while evocative, obscures the distinctively Indigenous character of the monument and its uses. Academic and Indigenous critiques of this framing have become increasingly visible in public discourse, encouraging a more nuanced understanding of the site's significance.

Where Do I Come In?

Professional archaeologists and archaeoastronomers can contribute by conducting rigorous, non-invasive surveys of the Bighorn Medicine Wheel and comparable sites using current remote sensing technologies. The application of LiDAR, Structure-from-Motion photogrammetry, and Geographic Information Systems to medicine wheel landscapes represents an immediate opportunity to advance documentation without physical disturbance. Researchers with expertise in atmospheric physics can revisit the stellar alignment debate using modern atmospheric modelling, potentially resolving questions that have remained open for four decades.

Ethnographers, anthropologists, and scholars in Indigenous studies are positioned to advance the most underrepresented dimension of medicine wheel research: the integration of oral traditions, ceremonial knowledge, and Indigenous astronomical traditions into the interpretive framework. This work requires sustained, trust-based partnerships with tribal communities and a willingness to respect the boundaries that knowledge holders place on the sharing of ceremonial information. Collaborative research models, in which Indigenous communities define the research questions and retain authority over the dissemination of culturally sensitive material, represent the most ethical and productive path forward.

Citizen scientists and amateur astronomers can contribute by conducting naked-eye observations at medicine wheel sites during critical astronomical events — particularly solstice sunrise and sunset — and documenting atmospheric conditions, visibility, and alignment accuracy. Such observations, systematically recorded and shared with academic researchers, could build a long-term observational dataset that complements the one-time survey methodology of previous studies. Amateur archaeologists and hikers who visit medicine wheel sites can contribute by reporting undocumented stone features to state archaeological surveys, particularly in the vast and under-surveyed Plains landscape where additional medicine wheels likely remain unrecorded.

Educators, museum professionals, and cultural interpreters can contribute by developing public programming that presents medicine wheels in their full cultural complexity — not merely as astronomical instruments but as expressions of Indigenous cosmology, sacred geography, and community practice. Accurate public interpretation helps counter reductive and sensationalised accounts while building broader support for the protection and respectful management of these sites.
