1986 Map of Lamar Canyon

USGS Topo · Published 1986

About this map

Yellowstone National Park reveals a wild, high-country landscape where the Lamar River and Slough Creek converge. This 1986 survey documents the intricate drainage systems of the Buffalo Plateau and the prominent volcanic topography of Specimen Ridge. The map illustrates the specialized wilderness infrastructure of the era, marking several segments of the Pack Trail system and a lone Corral near Crystal Creek. The presence of a Gravel Pit near the river indicates the localized maintenance requirements for the primitive roads through Lamar Canyon. Collectors of park history can trace the headwaters of numerous named tributaries, including Amethyst Creek, Jasper Creek, and Quartz Creek, which feed into the valley floor.
