1988 Map of Cross Canyon

About this map

Canyonlands National Park dominates this high-desert landscape at the confluence of several major geological features along the Colorado River. The western edge is defined by the deep carving of Cataract Canyon, where the river serves as the boundary between Garfield Co and San Juan Co. To the east, the terrain breaks into the distinct formations of The Needles, featuring landmarks such as Horsehoof Arch. The interior of the sheet reveals a complex network of drainage systems including Cross Canyon and Red Lake Canyon. Significant open basins and plateaus, such as Beef Basin, Imperial Valley, and Pappys Pasture, suggest the historical use of this territory for grazing and movement through the high country. The presence of Ruin Park points to the archaeological depth of this region, while names like Bobbys Hole and Calamity Grabens evoke the human history and geological instability of the era.
