1965 Map of Izzenhood Gap

About this map

Izzenhood Gap serves as a prominent landform in this high-desert portion of Lander County, as recorded by the Geological Survey during the mid-1960s. The landscape is primarily defined by its drainage and water resources, with Sixmile Creek cutting through the northern reaches of the quadrangle. Human activity in this arid environment is sparsely represented but critically placed, centered around the Izzenhood Well and its associated benchmarks. The presence of a Gravel Pit near the gap indicates local industrial use of the geological materials found in these mountains. This survey captures the region just as photogrammetric methods from 1963 aerial photography were being integrated into standard topographic mapping, providing a precise look at the unimproved roads and light-duty trails that crisscrossed the desert floor.
