2020 Map of Cold Bay C-1 SE

About this map

Alaska Peninsula terrain dominates this 2020 survey, where the glacial and volcanic history of the region is etched into the landscape. The topographic data reveals the dramatic drainage patterns of the Cathedral River, which carves through the southwestern portion of the map. This waterway is framed by the steep rising elevations of Cathedral Valley, a primary geographic feature that dictates the local hydrology. Unlike maps of more settled areas, this quadrangle highlights a wilderness defined by its natural contours and the absence of established road networks or permanent human settlements. The survey provides a precise record of the shoreline and interior mountain structures as they existed in the early 21st century, serving as an essential reference for understanding the shifting environmental conditions of the Aleutian region.
