1954 Map of White Canyon 4 NW

About this map

Jacobs Chair stands as a prominent landmark amidst the intricate drainage networks of San Juan County in the early 1950s. This preliminary survey, based on 1951 aerial photography, details the rugged erosional landscape where White Canyon meets several significant tributaries, including Gravel Canyon and Fry Canyon. The map records essential points of passage across this difficult terrain, notably Soldier Crossing and Gravel Crossing, which were critical for local travel before the development of modern infrastructure. Evidence of early resource exploration is found at a specific Prospect located near the northern reaches of the canyon system. Small-scale water management is also visible through the presence of a Reservoir and the naturally occurring Rock Spring, highlighting the fundamental importance of water sources for those navigating the arid uplands of Moss Back and the surrounding mesas.
