Figure 1

Sierra Nevada Ecosystem Project (SNEP) study area showing the areas surveyed by Leiberg (1902), Sudworth (1900), and Fitch (1900a, b; Sonora and Yosemite quadrangles, left to right, respectively) in the late nineteenth century. National Forests (NF) and National Parks (NP) north to south include Modoc NF, Lassen NF, Lassen NP, Plumas NF, Tahoe NF, Lake Tahoe Basin Management Unit, Eldorado NF, Stanislaus NF, Yosemite NP, Inyo NF, Sierra NF, Sequoia and Kings Canyon NPs, and Sequoia NF. Within Leiberg’s study area, major gold belts or veins occur within national forest boundaries (Plumas and Tahoe NFs), but they primarily occur below the elevation of the national forests south of Leiberg’s study area (gold belts or veins adapted from Clark 1970).
