About this map

Dinosaur National Monument dominates this mid-1950s survey, defined by the powerful carving force of the Green River as it cuts through Split Mountain. This section of the river is a high-energy corridor of whitewater, featuring named hazards such as Moonshine Rapids, SOB Rapids, Schoolboy Rapids, and Inglesby Rapids. The landscape transitions from the sheer canyon walls and high elevations of the Yampa Plateau to the valley floor along Cub Creek.

Human activity is concentrated in the southern flats, where Morris Ranch and Daniels Ranch represent the region's agricultural history. Local navigation is marked by the Daniels Trail and a remote Landing Strip, while a Gaging Sta along the river monitors the water flow. The map reveals a wild terrain where isolated springs like Elder Spring and Warm Springs provided vital water for livestock and early inhabitants of this corner of Uintah County.
