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.

To the south, the terrain transitions into the agricultural expanse of Knights Valley. The small settlement of Kellogg sits near the confluence of Redwood Creek and Yellowjacket Creek, featuring a local Cem and Fish Hatchery. Throughout the rugged interior, family-named landmarks like Locke Cabin, Turner Flat, and Bacon Flat indicate a history of isolated homesteads and high-altitude ranching reached by routes like the Appletree Trail.
