2014 Map of Signal Mountain

Evidence of local history and early activity is found at the Signal Area Cem and the naming of Arrastra Canyon, which suggests early prospecting or mining efforts. The southern boundary is defined by the Artillery Mountains, while prominent landmarks like Blue Rock and Signal Canyon assist in orienting travelers through the rugged terrain. Transportation routes such as Alamo Rd and Signal Rd follow the natural topography, linking the river valley to the higher elevations of the surrounding mountains.
