About this map

Emigrant Gap and the surrounding high Sierra terrain are defined here by a dense network of early industrial and transportation infrastructure. The Southern Pacific railroad follows the ridge line above the South Yuba River, serving mountain settlements like Cisco and Cisco Grove. The landscape is a complex map of water management, featuring the Bowman Spaulding Conduit and the Drum Canal, which link major reservoirs such as Bowman Lake and Lake Spaulding.
