Split Rock and the volcanic depressions of Butte Crater define this high-altitude landscape along the border of Clark and Fremont counties. Surveyed in the early 1970s, the terrain is characterized by its geological features, including several named caves and an Ice Cave located in the northern reaches. The area is intersected by a network of primitive transportation routes, most notably the Red Road and Crooked Road, which suggest a remote region utilized for seasonal access rather than permanent settlement. The presence of a Drill Hole and scattered wells indicates exploration and resource management within this volcanic field. This sheet provides a detailed view of the natural topography before more modern developments, preserving the original paths of the Jeep Trail and connections toward Sand Creek Road.
