Trail erosion and shifting ground level complicate contextual inference
Claim about Kodachrome Basin Handprints · Stance: observational
The survey reports specific heights above ground for low handprints, implying that changing ground level (erosion/deposition/traffic) can distort interpretations about who could reach which impressions and when.
Site
- Kodachrome Basin Handprints Cannonville, Utah, United States
Evidence for and against
- UGS GeoSights field article describing the handprints and setting (2024)
- UGS measurement: lowest handprint height above ground
- UGS access description from Panorama trailhead to shelter
Other claims about Kodachrome Basin Handprints
- The age and authorship of the handprints are not established
- 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
- Modern visitors are likely deepening at least some grooves
