1958 Map of East Portal

USGS Topo · Published 1983

About this map

The Continental Divide defines the spine of this high-altitude landscape, where the Arapaho and Roosevelt National Forests meet. Transportation history is deeply etched into the terrain, most notably at the Moffat Tunnel, which pierces the range near the settlement of East Portal. This engineering feat bypassed the treacherous heights of Rollins Pass, where the Old Railroad Grade and the Corona site remain as physical evidence of the earlier, wind-swept rail route over the crest.
