Signal sits in a high desert landscape of the Mojave Desert, where the survival of early settlements was dictated by reliable water sources like Signal Spring and the drainage patterns of seasonal desert washes. The presence of the Signal Area Cem near the townsite suggests a long-standing community tied to the land, while the remote infrastructure of McCracken Mine Rd and Alamo Rd points to a history of resource extraction and transit through this arid reach of Mohave County.
