John Muir National Historic Site, situated on the slopes of Mt Wanda and Mt Helen, anchors the northeastern corner of this 2021 landscape. The map details a sophisticated network of water infrastructure and conservation lands, defined by the Mokelumne Aqueduct and the large basins of San Pablo Reservoir, Briones Reservoir, and Lafayette Reservoir. These reservoirs are carved into a series of prominent ridges, including Sobrante Ridge and the Berkeley Hills, which separate suburban enclaves from protected open space.
