1948 Map of Los Alamos

Transportation and water access are dictated by the terrain, with numerous seasonal drainages such as Cañada de los Alisos and Cañada de Santa Rosa carving through the uplands. Roads follow the natural contours of the land, notably through Drum Canyon and the Santa Rita Valley. The map illustrates a transitional era where the local economy remained tied to the geography of the canyons, including Cebada Canyon and Crawford Canyon, before the further expansion of modern infrastructure.
