The Pacific Ocean dominates this coastal survey along the Sonoma County shoreline. This particular sheet captures the transition from land to sea, with the maritime boundary and the Public Land Survey System demarcation of t11n r15w serving as the primary geographic markers. The coastline itself is defined by steep contours that descend rapidly into the deep waters of the Pacific, reflecting the dramatic geology characteristic of this stretch of northern California. While largely a marine-focused study, it provides precise documentation of the shoreline's position in 2018.
