1980 Map of Poncha Pass

USGS Topo · Published 1991

About this map

Poncha Pass serves as the central focal point of this 1980 survey, marking the topographic divide between the San Isabel National Forest and Rio Grande National Forest. The landscape is defined by the high-altitude transit routes that have historically connected the Arkansas Valley to the San Luis Valley, most notably an Old Railroad Grade and the route toward Marshall Pass. These corridors parallel Poncha Creek, tracing the paths once vital to the region's mountain rail system.
