The Charleston quadrangle lies on the south edge of a structural and topographic saddle between the Wasatch Range and Uinta Mountains. The quadrangle includes the southern part of Heber City and Heber Valley and the northern half of Round Valley, as well as parts of Deer Creek Reservoir and Wasatch Mountain State Park; the small communities of Charleston, Daniel, and Wallsburg are also in the quadrangle. The quadrangle also straddles the north edge of the Charleston-Nebo thrust sheet, and thus includes three distinct groups of rocks: (1) a nearly complete section of allochthonous Pennsylvanian rocks of the Oquirrh Formation that comprises the Charleston thrust plate; (2) para-utochthonous, southeast-dipping Jurassic and Triassic strata (Thaynes Limestone, Ankareh Formation, Nugget Sandstone, and Twin Creek Limestone) below the Charleston thrust; and (3) parts of the Big Cottonwood Formation (Upper Proterozoic), Tintic Quartzite (Middle to Lower Cambrian), and the Great Blue Limestone and Humbug Formation (Upper Mississippian), which are exposed in a structurally complicated zone between the Charleston thrust and Deer Creek detachment faults. A variety of late Tertiary and Quaternary deposits record the evolution of the present landscape.

This geologic map and report provide basic geologic information necessary to further evaluate geologic hazards and resources in the area, and to gain an understanding of the geology upon which this landscape developed. Contains two plates, the geologic map and explanation sheet, and an accompanying report, each.
