Mahnke Peak

Mahnke Peak is in Mendocino County, California, in the Mayacamas Mountains of the northern California Coast Ranges.[1] It is just south of the Mendocino County–Lake County boundary. It is 0.3 miles (0.48 km) east-southeast of the heading of Hoil Creek, 7 miles (11 km) northwest of Cobb Mountain and 8 miles (13 km) south of Kelseyville.[2]

The Köppen climate classification is Csb : Warm-summer Mediterranean climate.[3] The mountain is named for John Christian Christof Mahnke (1858–1939) and his family, who ran several hundred head of angora goats on this peak for 70 years.[4][2] There is a small building on top of the peak which has an excellent view of the power plants of The Geysers geothermal field.[5]

The peak borders the Russian River watershed to the west.[6] It is 0.3 miles (0.48 km) east-southeast of the heading of Hoil Creek.[2] To the northwest Hoil Creek joins Tyler Creek, a tributary of Pieta Creek, which in turn is a tributary of Russian River. Another stream draining the peak is Hummingbird Creek, which flows south to Squaw Creek, a tributary of Big Sulphur Creek, which is also a tributary of Russian River to the west.[7]

Mahnke Peak is 3,652 feet (1,113 m) high with a prominence of 612 feet (187 m). It has isolation of 5.84 miles (9.40 km) from Mount Hannah to the east-northeast.[1]
