The Red Ledges 7.5-minute quadrangle is located in the southern most portion of the southern Snake Range (SSR), a Cordilleran metamorphic core complex (e.g., Coney and Harms, 1984). The mapped area is within the upper plate of the southern Snake Range dcollement (SSRD) and was one of the first locations where extension along a detachment was recognized as Tertiary in age (e.g., Armstrong, 1972). Portions of this quadrangle were previously mapped at the 1:147,300 scale (north of the White Pine-Lincoln county line) (Hose and Blake, 1970) and at the 1:200,000 and 1:250,000 scale (south of White Pine-Lincoln county line) (Tschanz and Pampeyan, 1961, 1970). Armstrong (1972) included a generalized geologic map of the northwest corner of the quadrangle. All of these maps show multiple extensional structures, bedrock composed of Paleozoic carbonates/siliciclastics, and generalized Tertiary volcanic units and Quaternary units (Tschanz and Pampeyan, 1961; Hose and Blake, 1970; Armstrong, 1972). The new geologic mapping at the 1:24,000 scale documented the extensional structures in more detail, differentiated the Tertiary volcanic units using new 40Ar/39Ar dating, and defined several new Tertiary volcaniclastic and Quaternary units.
