About this map

George Air Force Base dominates the northeastern landscape of this mid-century survey, its expansive runways and facilities situated just east of the growing community of Adelanto. The map reveals a transition from the structured military installation to the surrounding High Desert terrain, where a network of residential and access roads begins to define the local geography. Significant thoroughfares like Pearblossom Highway and Sunrise Valley Road cut through the arid flats, connecting small clusters of settlement at Mountain View and Adobe Corners.

The presence of numerous infrastructure points, such as a prominent Levee near the base and scattered irrigation features like Water Tanks and Wells, illustrates the effort to manage water and territory in San Bernardino County. Researchers can trace the early residential grid along Bartlet Ave and Duchess Ave, contrasting the dense town layout with the wide-open expanse of Baldy Mesa Road to the south.
