2022 Map of Alleghany
USGS Topo · Published 2022About this map
Alleghany serves as the central hub for a landscape defined by deep ravines and high ridges within the Tahoe National Forest. The map documents a historical footprint of gold-era activity, evidenced by the numerous cemeteries including the Forest City Cem and Minnesota Flat Cem, which sit atop hillsides once bustling with hydraulic and hard-rock mining. Settlement patterns follow the topography of the benches or flats, such as Moores Flat and Orleans Flat, which overlook the steep drainage of the Middle Yuba River. Transportation is shaped by the complex terrain, with routes like the Foote Crossing Rd and the Pliocene Ridge Rd connecting these remote outposts. The network of water management features, including the Plum Valley Ditch Trl and Irwin Ditch Rd, illustrates the intensive effort to redirect water across San Juan Ridge for industrial use.
