About this map

The United States and Mexico border defines the southern extent of this 2021 survey, where the rugged terrain of Santa Cruz County meets the international line. This high-desert landscape is anchored by the Pajarito Mountains and the prominent Mojohave Ridge, protected within the Coronado National Forest. The geography is shaped by significant drainages including Tonto Canyon and Alamo Canyon, where the namesake Alamo Spring provides a critical water source in an otherwise arid environment.

Evidence of ranching and water management is visible through a series of cattle tanks like Childdote Tank, Coyote Tank, and Border Tank. Remote access across this difficult terrain is limited to primitive paths such as the Sycamore Canyon Trl and the Border Trl, illustrating the isolated nature of the borderlands. These features highlight the specialized infrastructure required for land management and border monitoring in a region where elevation and water dictate human movement.
