The tallest mountain in the Mayacamas Mountains of California
Its 4720+ feet main summit is located in Lake County, west of the town of Cobb. Like nearby Mount Saint Helena, Cobb Mountain is tall enough to receive winter snowfall. The mountain also has a sub-peak named Cobb Mountain – Southwest Peak with an elevation of about 4483+ feet. Southwest Peak lies on the Sonoma-Lake county line and is the highest point in Sonoma County. Nearby tall peaks like Mount Saint Helena and Snow Mountain can be seen from this summit.
History of Cobb
Named after John Cobb - the first pioneer to settle in the area
Cobb was born in Henry County, Kentucky on May 19, 1814. In 1853 he arrived in California and homesteaded in Cobb Valley and went on to become the county assessor and the road overseer for the Clearlake District in 1855. He built a combined saw and gristmill in 1859, which was later destroyed by fire. He sold his interests and moved to Napa County around 1860.
