The Calumet Mountains dominate the western portion of this 2021 survey, rising sharply from the surrounding alluvial fans within the Mojave Desert. This arid landscape is defined by the broad expanse of the Cadiz Valley to the east, illustrating a classic basin-and-range topography where steep peaks transition into vast desert flats. While the area lacks developed settlements or complex infrastructure, the map reveals the intricate drainage patterns and contour variations of the mountain range, providing a clear record of the terrain as it appeared in the early 21st century. The survey includes Public Land Survey System designations such as t2n r14e and t1n r15e, which are essential for identifying land tracts in this part of San Bernardino County.
