1962 Map of Jess Valley

About this map

Jess Valley forms a prominent agricultural and hydraulic basin within the high country of the Modoc National Forest. This 1962 survey, mapped by the U.S. Forest Service, highlights the intersection of public timberlands and private ranching interests, notably at the Blue Lake Ranch. The drainage of the South Fork Pit River and Mill Creek defines the northern reaches, while the southern topography is dominated by the steep ascent toward Mahogany Ridge and the recreation areas surrounding Blue Lake. The map details a network of early forest infrastructure, including a Guard Station and several remote water sources like Parsnip Springs and West Valley Spring. The transition from the flatlands of McKabe Flat to the deep incisions of Deep Canyon reflects the complex watershed management of the era, marked by designated Picnic Grounds and the Little Meadows Campground.
