Geologic Map of the Mollie Hogans 7.5' Quadrangle, Grand County, Utah (M-259dm)
By: Hellmut H. Doelling and Paul A. Kuehne
The Mollie Hogans 7.5' quadrangle covers a large part of Arches National Park and encompasses colorful bedrock strata ranging in age from Pennsylvanian Paradox Formation to Cretaceous Mancos Shale. Salt diapirs are common throughout the area, and the Salt-Cache Valley Salt Structure is the most prominent structure, with several additional salt structures present, including the Salt Wash and Courthouse synclines and the Elephant Butte folds. Scenic resources in the area showcase joints, fins, grabens above salt walls, and the highest concentration of arches in the world.
