This is a digital copy of ‘Mount Hayes’, a topographic map printed by the US federal government.
It is part of the Joint Operations Graphic (Air) series at 1:250,000. These topo maps are available throughout the Americas, and they portray the landscape more effectively than United States Geological Survey quads at the same scale. JOGs have the same attention to detail as 1×2 degree quadrangles, but their layer coloring, relief shading, landmarks, and minimal clutter give them superior legibility in the outdoors.
Key details of the printed map:
- edition 3
- reprinted in April 1994
- published by the Defense Mapping Agency, Aerospace Center
- air information current through January 23, 1981
- base map compiled in November 1976
