About this map

Jericho Valley and Jerusalem Valley are central features of this California interior landscape, where the borders of Lake, Yolo, and Napa counties converge. The terrain is defined by complex drainage patterns, with Jericho Cr and Putah Cr carving through high ridges such as the Watson Range and Little Blue Ridge. In the southern reaches, peaks like Jim Davis Peak and Jim Dollar Mtn overlook a series of small, isolated water bodies including Amel Lake and Wildcat Lake.

Remote roads and trails such as Jerusalem Grade and Hoyes Ranch Rd provide the only access to these upland valleys. Notable named landmarks like The Cedars and Hells Half Acre indicate a landscape shaped by distinct geological or botanical characteristics. Historically, the area represents a rugged cattle-ranching and timber interior, where early 21st-century mapping still records many family-named peaks and traditional valley identifiers.
