1959 Map of Mount St. Helena

USGS Topo · Published 1966

About this map

The Mayacmas Mountains dominate this 1959 survey, rising to the prominent summit of Mount St Helena, where a lookout and VABM 4343 station are noted. The landscape reveals a legacy of quicksilver and mineral extraction, particularly in the northern reaches where several distinct operations are clustered, including the Chicago Mine, Helen Mine, Wall Street Mine, and Jewess Mine. These sites reflect the intensive mining activity that once defined this portion of the border between Sonoma and Lake Counties.
