Hellmut H. Doelling and Paul Kuehne
The Thompson Springs quadrangle is located north of Arches National Park in eastern Utah. Exposed strata range from Early Cretaceous Cedar Mountain Formation to Late Cretaceous Castlegate Sandstone. The quadrangle overlies the ancestral Paradox basin and is influenced by salt-related folds, including the Salt Valley anticline to the west and Cisco Dome to the east.
