Less than 75 years after the discovery of gold in 1848, almost every grizzly bear in California had been tracked down and killed. One prospector in Southern California, William F. Holcomb (nicknamed "Grizzly Bill" Holcomb), was particularly well known for hunting grizzly bears in what is now San Bernardino County. Noted California mountain man Seth Kinman claimed to have shot over 800 grizzly bears in a 20 year period in the areas surrounding present day Humboldt County. The last hunted California grizzly bear was shot in Tulare County, California, in August 1922, although no body, skeleton or pelt was ever produced. Two years later in 1924, what was thought to be a grizzly was spotted in Sequoia National Park for the last time and thereafter, grizzlies were never seen again in California.
