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.
