Flaming Gorge - Green River, above Flaming Gorge

Green River, above Flaming Gorge. Sweetwater County, Wyoming. 1871. (Photo by E. O. Beaman). 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).
