Walter Springs stands at the heart of this Napa County landscape, situated at the junction of several prominent drainages including Pope Cr and Maxwell Cr. The northern reaches are defined by a complex series of valleys and ridges, most notably the intriguingly named Mysterious Valley and its corresponding Mysterious Valley Airport. The eastern boundary of the sheet is dominated by the northern fingers of Lake Berryessa, where the Eticuera Creek watershed meets the reservoir. Settlement patterns are concentrated along narrow road corridors such as Pope Canyon Rd and Berryessa Knoxville Rd, which navigate the steep topography between Turner Mtn and the various flats like Moore Flat and Gibson Flat. The map documents a rugged interior terrain characterized by seasonal creeks such as Adams Cr and Dyer Cr that feed into the larger water systems of the region.
