1892 Map of Henry Mountains

About this map

The Colorado River and San Juan River dominate this reconnaissance study of Southeastern Utah, tracing the deeply incised drainage systems before the mid-century creation of major reservoirs. The map centers on the high desert of San Juan, Garfield, and Kane counties, highlighting the dramatic monocline of the Water Pocket Fold and the isolated peaks of the Henry Mountains, including Mt Hillers and Mt Ellsworth. This edition reflects topography gathered by the Powell Surveys, capturing the region during an era of early federal conservation, evidenced by the inclusion of Rainbow Bridge National Monument and Natural Bridges National Monument. Along the southern border, the Utah Arizona Boundary Line passes through the iconic sandstone formations of Monument Valley and the steep walls of Piute Canyon, documenting the landscape just as it was becoming a point of national interest.
