Geology
The lithology of the Burro Canyon Formation is dominated by medium- to fine-grained sandstone, much of which has rounded chert and quartz pebbles above scour surfaces. The Burro Canyon Formation was deposited in a braided- stream system.
The formation overlies the Morrison Formation, and underlies the Mancos Shale Formation. It is similar to the Cedar Mountain Formation in the region.
Fossils
The Burro Canyon Formation preserves fossils dating back to the Early Cretaceous period of the Mesozoic Era.
