The Napa River valley floor transitions into the heights of the Mayacamas Mountains in this detailed survey of California's premier wine country. Long-established viticultural communities like Saint Helena, Rutherford, and Oakville are connected by the Silverado Trl and Main St, with smaller loading points like Thoman and Zinfandel marking the valley's agricultural infrastructure. The map documents significant local history sites, including the Saint Helena Public Cemetery and Catholic Cemetery at the base of the foothills near Sulphur Canyon. To the west, the landscape rises sharply toward Mt Saint John and Bald Mtn, crossing the boundary between Napa and Sonoma counties. The drainage network is complex, with Bale Slough and Conn Cr feeding the river, while Lake Hennessey and Lake Hinman provide essential water storage for the surrounding vineyards and the community of Yountville.
