Flaming Gorge

Flaming Gorge named by John Wesley Powell in 1869 “The Green River enters the range by a flaring, brilliant red gorge”. The rusty orange formation is comprised of 220 million-year-old mudstones deposited along the edge of shallow seas, on mudflats, flood plains and stream channels. Fluctuating seas left the varied gray and brown strata along with fossil shells, shark teeth and fish bones. Decomposition of the marine life has resulted in a phosphate-rich formation which is mined today for use as commercial fertilitzer.
