1951 Map of Upheaval Dome

About this map

Upheaval Dome sits at the center of this 1951 topographic study, anchoring a landscape where the Green River and Colorado River approach their confluence through deep, winding canyons. This era of mapping captured the remote canyons of San Juan County before the establishment of major national parks, documenting evidence of ancient habitation at the Cliff Dwellings near Aztec Butte. The map reveals a complex network of plateaus and basins, including Soda Springs Basin and the high Grays Pasture, accessible only by occasional routes like the Trail.
