Red Canyon Rim

The Red Canyon Rim, which forms the east side of the Red Canyon Valley, is comprised of salmon-colored Jurassic Nugget sandstone. The sandstone was deposited during regression of ancient seas. It represents a tidal flat and beach sedimentation as cross-stratified during deposition on ancient black-beach sand dunes. The canyon was formed some 60 million years ago during uplift of the Wind River Range to the West. As the sedimentary rocks tilted, the more easily erodable rocks were removed by the action of water, creating the canyon as it is seen today. Photo © copyright by Robert Faucher.
