About this map

Chiles Valley and its surrounding canyons define this interior portion of Napa County. The landscape is marked by several distinct basins, including Soda Valley and Elder Valley, which are separated by prominent rises like Trout Creek Ridge and the Cedar Roughs. These valleys are connected by a network of historic routes such as Chiles Pope Valley Rd and Lower Chiles Valley Rd.

Hydrological features are central to the area's character, anchored by the southern reaches of Lake Berryessa and its islands, Indian Island and Schoolhouse Island. Several natural water sources are documented, including Johnson Spring and Soda Spring, alongside the waters of Lake Hennessey at the southwestern corner. The terrain rises sharply to peaks like Baldy Mtn and Little Sugarloaf Peak, with drainage provided by numerous named creeks including Maxwell Cr, Pope Creek, and Sage Cr.
