Let the flowers guide your eyes across the diagonals of the Red Canyon, just south of Lander, Wyoming. The canyon was formed some 60 million years ago during the uplift of the Wind River range to the west. As the sedimentary rocks tilted, the more easily erodible rocks were removed by the action of water, creating the canyon as it is seen today.
The long, grass-covered slopes on the west side of the canyon are part of the Permian Phosphoria formation, a marine deposit composed of limestone, sandstone, dolomite, siltstone, bedded chert and phosphorite. The less-resistant rocks above the chert were eroded.
