Click here to see a collection of historic images of Flaming Gorge and Red Canyon of the Green River taken by the Powell Expedition of 1872. Website images include both standard photograph and 3D views (as anaglyphs - requiring red-and-cyan 3D viewing glasses).

This view shows the mouth of Flaming Gorge. Today Flaming Gorge Reservoir floods most of the Green River valley in this area.

Generalized stratigraphy after: Sprinkel, D.A., 2000, Geology of Flaming Gorge National Recreational Area, Utah-Wyoming: In Geology of Utah's Parks and Monuments, Sprinkel, D.A., Chidsey, T.C., and Anderson, P.B., eds., Utah Geological Association Publication 28., p. 277-299. Note that thicknesses of units are not to scale. The Proterozoic units alone are up to several tens of thousands of feet thick. Above the the Uinta Mountain Group scale of units are roughly one inch=1,000 feet, but units can be highly variable in thickness.

Stratigraphic unit information is modified from the USGS GeoLex (Lexicon of Geology): http://ngmdb.usgs.gov/Geolex/geolex_qs.html.
