1970 Map of Mount Adams East

USGS Topo · Published 1978

About this map

The Yakima Indian Reservation boundary defines the eastern half of this landscape, where the high ice of the Mount Adams Wilderness gives way to alpine meadows and volcanic fields. High-altitude landmarks like The Castle and Pikers Peak overlook a massive system of active ice, including the Klickitat Glacier and Mazama Glacier. Several disputed or historical survey lines, such as the Pecore Line 1920-22 and the Campbell Line 1906-07, are meticulously noted along the reservation border.
