These bluffs and buttes on the west side of the river are probably near
the Firehole Canyon Campground near the "Big Bend" (now Flaming
Gorge National Recreation Area). Today, Flaming Gorge Reservoir floods this
section of the Green River's floodplain. The nearly flat-lying shale and
ledge-forming sandstones (in this and the previous image) are of Late Cretaceous
age (Mancos Shale capped by Mesa Verde Group sandstones). |
