1921 Map of Cape Vizcaino

About this map

The Ten Mile River Logging RR lines the southern coast of this Mendocino County survey, reflecting the industrial timber operations that defined this shoreline during the early twentieth century. Working under the direction of Col. Chas. L. Potter, the Army Corps of Engineers captured a rugged coastal landscape where small settlements like Westport and Hardy clung to the bluffs above the Pacific Ocean. This reconnaissance reveals the logistical pattern of the era, where narrow-gauge rail and shipping points at Rockport Bay and Newport served as the primary links for isolated logging communities. From the Cottaneva Valley down to Inglenook, the terrain is marked by numerous drainage crossings such as Wages Cr and Juan Creek, highlighting the natural barriers overcome by coastal settlers and loggers before the expansion of modern highway systems.
