Ruby stands as a focal point in this high-desert landscape along the international border, surrounded by the peaks and drainages of the Coronado National Forest. This region is defined by a complex network of canyons and gulches, including California Gulch, Old Glory Canyon, and the prominent Tumacacori Mountains to the northeast. Water management in this arid environment is evident through a high density of named tanks and springs, such as Ruby Lakes, Yank Tank, and Savolta Spring, which supported the area's grazing and mining history. The southern edge of the survey follows the boundary between the United States of America and Mexico, where the terrain rises toward Flat Top Mtn. Notable landmarks like the Ramanote Canyon Natural Arch and trails like the Sycamore Canyon Trl reflect the preservation of this remote borderland.
