Figure 15.--Photographs of large-scale crossbedding,
interpreted as deltaic foresets, in the Minturn Formation. Differences
in mechanisms that produce large-scale concave and planar foresets
needs further investigation.
A) Concave-up foresets on east side of Rito
Alto Peak.
B) Planar foresets (labeled "large-scale
crossbedding") on east side of Phantom Terrace, about 3 km
south of Hermit Peak.
