1978 Map of Diamond Lake

USGS Topo · Published 1994

About this map

The Calapooya Mountains and the headwaters of the North Umpqua River dominate this 1970s landscape, illustrating a region defined by high-altitude hydrology and federal land management. Large reservoirs like Lemolo Lake and Toketee Reservoir are central to the terrain, supporting the descent toward Toketee Falls. The map reveals the intricate network of the Umpqua National Forest and adjacent timberlands, where small outposts like Steamboat and Mowich serve as solitary markers of human activity. To the south, the Pumice Desert near Crater Lake National Park offers a stark contrast to the dense drainage basins of Copeland Creek and Boulder Creek. This survey provides a record of the Cascades before modern infrastructure further altered these watersheds, highlighting remote industrial sites such as the Umpqua Mine and specialized transit points like the Toketee Landing Strip.
