1892 Map of Henry Mountains

About this map

The Henry Mountains dominate the northern landscape of this late nineteenth-century survey, rising sharply above the complex canyon systems of the central Colorado Plateau. This early topography, produced under the direction of J.W. Powell, documents the confluence of major desert waterways where the Colorado River meets the San Juan River. The map captures the dramatic geological structure of the Water Pocket Fold and the isolated peaks of Mt Hillers, Mt Pennell, and Mt Holmes. To the south, the northern reaches of the Navajo Indian Res. are delineated, extending toward the distinct landforms of Monument Valley and Navajo Mt. The intricate drainage patterns of Cataract Canyon and the Fremont River reveal a landscape defined by erosion and isolation before modern infrastructure reached this part of the Four Corners region, offering a clear record of the territory as it was known to early scientific expeditions.
