2018 Map of Cow Mountain

About this map

Mayacmas Mountains terrain dominates this 2018 survey of the border between Mendocino and Lake Counties. The landscape is defined by the high ridges of Cow Mtn and Little Cow Mtn, divided by drainages like Scotts Cr and N Fork Mill Cr. In the northeastern corner, the small settlement of Cooper sits near the headwaters of Mewhinney Cr, while the elongated Blue Lakes provide a striking visual break in the topography. A narrow passage known as The Narrows connects these water bodies, which are flanked by the winding Blue Lakes Rd. Notable landmarks for hikers and local historians include the Glen Eden Trl and Forty-Acre Opening, alongside numerous remote water sources such as Black Oak Springs. The map reveals a transition from these high peaks to the Bachelor Valley, illustrating the complex watershed system that feeds into Sulphur Creek and Cold Cr.
