The Center Creek quadrangle lies astride a structural and topographic saddle between the Wasatch Range and Uinta Mountains. The quadrangle includes three distinct groups of rocks: (1) allochthonous, Permian to Pennsylvanian Oquirrh Formation in the Charleston thrust plate that is deformed into two large, southeast-plunging folds; (2) parautochthonous, southwest-dipping Mesozoic strata beneath the Charleston thrust; and (3) subhorizontal, Oligocene to Eocene clastic and volcanic rocks that unconformably overlie older strata.
