About this map

The Colorado River carves a winding path through this corner of Grand County, Utah, defining a landscape of deep canyons and churning whitewater. This 2014 survey captures the river's descent through a series of named hazards, including Skull Rapids, Sock-It-To-Me Rapids, Last Chance Rapids, and the aptly named Funnel Falls. Away from the riverbanks, the terrain is marked by prominent landforms such as Big Triangle and Little Triangle, alongside numerous tributary systems like Agate Wash, Cottonwood Wash, and Triangle Canyon.

Evidence of early 20th-century transportation and industrial infrastructure appears along the western edge of the map. The Agate Siding and Cisco Pumphouse indicate the historical importance of the railroad and its associated water-pumping facilities in this arid environment. Other markers of human activity and natural resource potential include the Granite site and Cane Spring, which provide specific points of interest for those studying the regional development and water management history of the plateau.
