1963 Map of The Twins

USGS Topo · Published 1981

About this map

Deschutes National Forest and Willamette National Forest converge at the high-altitude volcanic landscape of the central Cascade Range. The map area is defined by a dense network of glacial lakes and volcanic summits, notably The Twins and Maiden Peak. For recreation and transport, a significant primitive trail system is documented, including the long-distance Skyline Trail and the Crane Prairie Trail, which navigate between prominent water bodies like Charlton Lake and Bobby Lake. The terrain is characterized by high-elevation meadows, such as Round Meadow and Poverty Meadows, and numerous volcanic features like Gerdine Butte and Charlton Butte. This 1963 survey, updated with 1970s aerial data, provides a detailed record of the wilderness boundary between Lane and Deschutes counties before modern development altered these backcountry routes.
