Jacumba Hot Springs serves as the focal point for this 1940s borderlands survey, situated where the Jacumba Valley meets the international boundary between the U.S. and Mexico. The landscape is dominated by the Jacumba Mountains and the engineering feat of the San Diego and Arizona Eastern railroad, which snakes through the high desert with stops at Dos Cabezas Siding and Carrizo Gorge Siding.
