The Central Sierra Historical Society and Museum, Inc. is a 501 (c)(3) public benefit corporation with a membership of over 500 individuals, businesses, and organizations. This grassroots endeavor was the catalyst for the Central Sierra Historical Society, which identified as part of its mission the creation of a regional history museum. CSHS launched the Museum of the Central Sierra with a major media event in 1998. In addition to museum building, CSHS is actively preserving local historical treasures, such as the Pine Logging Camp and a 1912 caboose from the SJ&E Railroad and collecting the oral histories of area pioneers.

The site offers information about the society and contains coverage of past events.
