Parent range California Coast Ranges

The Mayacamas Mountains are located in northwestern California in the United States. The mountain range is part of the Northern Inner Coast Ranges, of the California Coast Ranges System.

The Mayacamas Mountains are located south of the Mendocino Range, west of Clear Lake, and east of Ukiah in Mendocino and Lake Counties, and extend south into Napa and Sonoma Counties. The range stretches for 52 mi (80 km) in a northwest-southeasterly direction.

The range's highest point is Cobb Mountain, at 4,724 ft (1,440 m) in elevation, located in the central section. There are several other peaks over 2,500 ft (762 m), including Mount Saint Helena and Hood Mountain. These peaks are sufficiently high to retain some snow cover in winter.

Several streams rise in the Mayacamas Mountains including Mark West Creek, Sonoma Creek, Calabazas Creek, Arroyo Seco Creek, Putah Creek, and Santa Rosa Creek.

In prehistoric times, around ten million years ago, the mountains are thought to have been densely forested in Mendocino Cypress (Cupressus pigmaea).

The Mayacamas Mountains currently support California mixed evergreen forest and California interior chaparral and woodlands habitats.
