Geologic map of the Big Bend quadrangle, Grand County, Utah (M-171)

By: H. H. Doelling and M. L. Ross The Big Bend quadrangle is named for a deeply incised meander bend in the Colorado River in southern Grand County, Utah. It is part of Utah's scenic Red-Rock country and includes the world-famous Delicate Arch and parts of Cache, Castle, and Professor Valleys. The quadrangle lies in the fold-and-fault belt of the northern Paradox basin, a northwest-trending asymmetrical basin that formed adjacent to the ancestral Uncompahgre uplift during Pennsylvanian to Late Triassic time.
