1903 Map of Hayden Peak

About this map

Hayden Peak serves as a central anchor for this survey of the High Uintas, where the headwaters of several major Western river systems originate. The terrain is defined by the sharp divide between the Wasatch National Forest and the Uinta National Forest, a boundary that also separates Summit and Wasatch Counties. At the turn of the century, these high-elevation basins remained a labyrinth of glacial lakes and alpine summits, including the notable Grandaddy Lake and Brown Duck Lake. The survey, conducted by W.J. Lloyd and Jeremiah Ahern, captures the drainage patterns of the Bear River, Provo River, and Duchesne River as they spill away from the central crest. The northern margin is defined by the Utah-Wyoming Boundary Line, illustrating the early 20th-century geopolitical layout of this mountain wilderness before modern road networks arrived.
