About this map

Mount George and the towering Twin Sisters dominate this topography along the border of Napa and Solano counties. The landscape is defined by a series of north-south running ridges and valleys, hosting a network of reservoirs including Lake Curry, Lake Madigan, and Lake Frey. In the southeast, the residential and agricultural reaches of Green Valley extend toward the hills, while the higher elevations feature prominent landmarks like Jenkins Rock and the Sugarloaf peak.

A complex hydrologic system is visible, with Suisun Cr and Green Valley Cr draining the eastern slopes. The transition from the more developed western edge near Tulucay Cr to the protected watershed areas around Wild Horse Valley reflects the region's managed balance between rural expansion and water conservation. Local landmarks like Green Valley Falls and Tindle Spring mark points of interest within the canyons, while named routes like Monticello Rd and Wooden Valley Rd trace the historic corridors through the Vaca Mountains foothills.
