1981 Map of Haypress Valley

About this map

Tahoe National Forest terrain dominates this landscape along the crest of the Sierra Nevada, where the headwaters of the North Yuba River and Middle Yuba River are shaped by historic resource extraction. Evidence of the region’s mining heritage is scattered across the ridges, from the Kentucky Mine and William Tell Mine in the west to the Pride Mine and 1001 Mine further east. These sites reflect the intensive gold-seeking efforts that once defined the local economy before the area transitioned toward modern recreation and water management. Modern infrastructure like the Milton-Bowman Tunnel and the Milton Reservoir illustrate the mid-century engineering required to harness mountain runoff. High-elevation lakes, including Sardine Lake and Volcano Lake, provide the backdrop for seasonal hubs such as Bassetts and the Sardine Lake Resort, connected by the Gold Lake Highway.
