About this map

Modoc National Forest encompasses this high-elevation landscape in northeastern California, where the drainage of Boles Creek shapes the local topography. This 1990 provisional survey documents a network of vital water sources and seasonal meadows essential for both timber management and grazing. The central Pothole Valley is flanked by prominent rises including Blue Mountain and Timbered Ridge, illustrating the transition from open meadowlands to dense coniferous slopes.

Strategic water points like Quaking Aspen Spring, Bird Spring, and Pothole Spring are meticulously mapped, alongside the Timbered Ridge Reservoir. These named springs and the expansive Boles Meadow indicate a land used heavily for resource extraction and forestry during the late twentieth century, before more modern digital mapping standardizations. The inclusion of Bird Spring Ridge and other landmarks provides a detailed record of the forest's interior before significant ecological or management shifts in the region.
