The Logan, Utah 7.5 minute quadrangle is underlain by Paleozoic sedimentary rocks of the western Bear River Range, and Tertiary rocks and Quaternary sediments deposited in the Cache Valley. Paleozoic rocks are predominantly limestones and dolostones of Late Cambrian through Pennsylvanian and Permian(?) age. Clastic sedimentary rocks make up the rest of the section. Paleozoic rocks record deformation during the Cretaceous Sevier orogeny. In the central two-thirds of the quadrangle, the Providence Canyon thrust fault places Ordovician through Devonian rocks, which are overturned to the west, on Devonian and Mississippian rocks that form the west limb of the Logan Peak syncline.
