TitleGypsum in Cutler Group (Permian), at Comb Wash, southeastern Utah
DescriptionThe Cutler Group is a highly variable group of Permain formations, generally appearing as irregular layers of dark red, lumpy sandstones, mudstones and conglomerates. At places such as Monument Valley, Cutler Group rocks are major cliff formers. Cutler Group sediments were deposited as alluvial fans and rivers from the ancient Uncompaghre Mountains (also called the ancestral Rockies) about 245-286 million years ago. Here we see white gypsum nodules that precipitated within Cutler red beds.
