About this map

Quartz Mountain and its namesake pass anchor this high-country landscape in Lake County, serving as a hub for both transit and mountain recreation. The 2011 survey reveals a complex water management system through the high flats, characterized by the Butcher Flat Reservoir, Holbrook Reservoir, and Lofton Reservoir. These catchments, along with named features like Tule Pond and Petes Puddle, suggest a landscape historically shaped by the needs of range management and seasonal water storage in an otherwise arid timbered environment.

Settlement patterns are represented by small, specialized outposts such as Ewauna Camp and Angel Camp, while the Quartz Mountain Sno-Park highlights the area's contemporary use. From the volcanic heights of Owen Butte and Quartz Valley Mountain to the lower reaches of Grasshopper Flat, the map traces the drainage of the South Fork Sprague River and the headwaters of Quartz Creek. The intersection of drainage basins and high mountain passes makes this a critical document for understanding the geographic orientation of Oregon's eastern interior.
