2015 Map of Adin Pass

About this map

Lost Cabin Mine sits tucked within the western slopes of the Modoc National Forest, a reminder of the prospecting history in this corner of Northeastern California. The landscape is defined by its transition from high summits like Schaffer Mtn and Grouse Mountain down toward the open expanse of Round Valley and the prominent escarpment known as The Cliffs. Transportation in this area is characterized by an intricate network of spurs and tracks, such as Adin Pass and Thompson Terrace, which provide access to numerous water sources including Niles Spring, Rice Spring, and Hoskins Spring. These high-country flats, notably Roney Flat and Rice Flat, once served as crucial points for seasonal movement and grazing. The topography is deeply carved by drainage systems like Dutch Flat Canyon and Niles Canyon, illustrating the complex watershed that feeds the northern California interior.
