1969 Map of Lonoak

About this map

The San Andreas Rift Zone dominates the central topography of this 1969 survey, slicing a distinct path between the Bitterwater Valley and the uplifted slopes of Mustang Ridge. This geologically active corridor defines the local settlement pattern, with the small community of Lonoak and the gathering point at Tully Hall positioned along the primary transit routes of Lonoak Road and Lewis Creek. The landscape is a mosaic of steep canyons and broad alluvial valleys, where water is the most critical resource, evidenced by the numerous named springs such as Greentree Spring, Hidden Spring, and Fourth of July Spring.
