1987 Map of Halls Crossing NE

About this map

Emigrant Trail tracks across this high desert landscape, offering a window into the historic movement of people through the difficult terrain of San Juan County. This 1980s-era survey documents the intersection of deep canyon geology and modern water management following the creation of Lake Powell, which fills the lower reaches of Glen Canyon. The map records the complex drainage systems of Moqui Canyon and North Gulch before they reach the reservoir's edge. This provisional mapping illustrates how human activity is limited primarily to the Glen Canyon National Recreation Area and specialized sites like a remote Gravel Pit. The presence of Lake Canyon in the southwest provides additional detail on the winding tributaries that define this portion of the Colorado River plateau.
