1942 Map of Arched Rock

USGS Topo · Published 1956

About this map

Little Black Mountain overlooks a steep coastal landscape where the land meets the Pacific Ocean north of the Russian River mouth. Surveyed in 1942, this map depicts the intricate drainage system of the Muniz region, defined by deep incisions like Russian Gulch and its several branches, as well as Meyer Gulch and Jewell Gulch. The shoreline is marked by prominent natural landmarks that served as vital navigation points, including the namesake Arched Rock, Goat Rock, and the cluster of Mile Rocks. This study captures the rugged topography of the Sonoma coast before modern development, showing the original winding coastal road and the isolated character of the drainages flowing westward into the sea from the higher elevations of the coastal range.
