The Jackson quadrangle in northwestern Utah comprises lowland of the Great Salt Lake Desert, the eastern part of Pigeon Mountain, and part of the Little Pigeon Mountains. Pigeon Mountain, at an elevation of 1555 m, is the highest point in the quadrangle. The lowland comprising about 95 percent of the quadrangle ranges in elevation from 1320 m to 1288 m, with most of the area under 1298 m. Mountainous parts of the Jackson quadrangle are underlain by Devonian and Permian sedimentary rocks of the Cordilleran miogeocline. These strata, which accumulated under shallow-marine conditions on the ancient continental shelf, are similar in most respects to those at Lemay Island. The remainder of the quadrangle is covered by surficial deposits of Quaternary age, including alluvium, lake sediments, and eolian sand. Much of the Quaternary sediment was deposited in Pleistocene Lake Bonneville, which covered the entire quadrangle at its high stand. The major structural features and physiography of the quadrangle-mountain ranges composed of pre-Cenozoic rocks and broad valleys filled with thick sequences of Cenozoic strata-resulted from one or more episodes of upper crustal extension in Neogene time.
