About this map

Toiyabe National Forest dominates the high-elevation terrain of this 1970s survey, where the peaks of Haskell Peak and Little Haskell Peak overlook a complex system of drainage canyons. The map documents a rugged landscape defined by Evans Canyon, Dark Canyon, and Donkey Canyon, transitioning from the mountain heights down to the Upper Long Valley. This area represents a vital transport corridor along the California and Nevada border, where the Western Pacific railroad tracks parallel Long Valley Creek through the eastern lowlands.

Evidence of ranching and early settlement is preserved through labels like Balls Ranch and the community of Purdy, situated near the headwaters of Purdy Creek. The presence of a Prospect and the winding Jeep Trail network suggests a history of resource exploration and high-country access. Researchers will note the convergence of several administrative boundaries, including the meeting points of Lassen and Sierra counties in California with Washoe County in Nevada, centered near the settlement of Peavine.
