1980 Map of Poncha Pass

About this map

Poncha Pass serves as the central focal point of this 1980 survey, marking a vital transition between the San Isabel National Forest and Rio Grande National Forest. The map documents a landscape defined by its extractive and transit history, featuring an Old Railroad Grade that winds through the mountainous terrain alongside Poncha Creek. Evidence of local industry is scattered throughout the drainages, with numerous prospects, a mine, and several quarries indicated near Mears Junction. Beyond the transit corridors, the geography is punctuated by significant peaks such as Poncha Mountain and Methodist Mountain, while natural water sources like Murphy Hole Springs and Poncha Hot Springs highlight the geothermal and hydrological character of this high-elevation region.
