## History

Grizzly Flats originated as a gold mining camp in the 1850s. The name was given by prospectors who were surprised by a grizzly bear there in 1850. In 1852 it was described as being on a flat piece of land measuring approximately one mile by three quarters of a mile and having two combination bars, stores, and boarding houses, with more under construction. It was located centrally in a jurisdiction called Mountain Township. A post office opened in 1854, a stagecoach route to Diamond Springs in 1855, and a Wells Fargo office in 1857. Catholic and Methodist churches were also established in the mid-1850s.
Fires in 1866 and 1869 destroyed most of the settlement; the 1869 fire killed one person and destroyed all but two buildings in the business district, which was only partly rebuilt.
On August 17, 2021, the Caldor Fire destroyed around 500 buildings in and near Grizzly Flats, including the original 1850s post office, the modern post office, and Walt Tyler Elementary School. Two people from the area with serious injuries caused by the fire were airlifted to hospitals. The mandatory evacuation order was lifted on September 6.
