1954 Map of Hells Canyon

About this map

The Yampa River snakes through the northern portion of this landscape, carving deep canyons and creating landforms like Castle Park and Hospital Hill. This mid-century survey captures a transition in land use within the Dinosaur National Monument, documenting several homesteads and seasonal sites including Mantle Ranch and Mantle Summer Camp. Notable for genealogists are the numerous family-named locations such as the Donald Wall Place and Robison Place, alongside several sites already marked as abandoned by 1954, including the Red Rope Ranch (Aband) and Caldwell Place (Aband).
