GEOLOGIC MAP OF THE KELTON PASS QUADRANGLE, BOX ELDER COUNTY, UTAH, AND CASSIA COUNTY, IDAHO
Michael L. Wells
The Kelton Pass quadrangle, located at the east end of the Raft River Mountains, is a classic metamorphic core complex, in part exemplified by the Raft River detachment fault. The area contains Archean metamorphic, Proterozoic metasedimentary, and Paleozoic carbonate and clastic rocks that were intensely deformed and thinned by alternating episodes of contraction and extension during the late Mesozoic to Cenozoic. Miocene to Quaternary sediments fill structural basins, and late Pleistocene Lake Bonneville deposits blanket low areas.
