The age and authorship of the handprints are not established
Claim about Kodachrome Basin Handprints · Stance: observational
No direct dating is presented for the carvings; observations of spalling/weathering and varying smoothness are used to argue for potentially mixed or multi-phase formation, but conclusions remain uncertain.
Site
- Kodachrome Basin Handprints Cannonville, Utah, United States
Evidence for and against
- UGS observations: spalling/weathering patterns and mixed surface textures
- UGS note: visitor touching likely deepens grooves ("statue rubbing" analogy)
- Critical travel/field note: emphasizes uncertainty and discourages overconfident origin claims
Other claims about Kodachrome Basin Handprints
- Alternative hypothesis: the handprints are ancient Indigenous ritual marks (disputed)
- Friable Gunsight Butte Member sandstone makes hand-imprinting plausible
- A Panorama Trail shelter contains more than 100 hand-shaped grooves
- Alternative hypothesis: some ‘handprints’ could be natural cavities later emphasized (disputed)
- The grooves are described as petrosomatoglyphs formed by repeated hand-rubbing
- Management tension: access vs preservation for a touch-sensitive site
- Kodachrome’s sandstone ‘pipes/spires’ have competing origin explanations
- Trail erosion and shifting ground level complicate contextual inference
- Modern visitors are likely deepening at least some grooves
