The Indian Valley Museum was established in 1973 to preserve the history of Indian Valley and the surrounding area. This history includes that of the Native Americans, early settlers, miners, ranchers, loggers, and the towns and settlements of the region.

The museum houses more than 1,000 artifacts representing the period from the 1860s through 1940. Over 600 pictures are on display showing early life in the valley. Mannequins wearing clothing typical of the late 1800s are seated in a restored surrey. Collections of Maidu Indian baskets, arrowheads and artifacts are displayed. Detailed explanations are posted throughout, giving the visitor an insight into the purpose and use of the various tools and implements and into the lives of the early inhabitants. Outside of the museum, there are exhibits of large mining, logging and farming equipment. See the website link above for days and hours open. Admission is free.

The Greenville Cy Hall Memorial Museum temporarily closed in August of 1996, when it relocated to the Miller Warehouse - one of the few remaining original buildings in Greenville. The Miller Warehouse was donated to the community by Evelyn Hall, wife of the late Cy Hall. Cy served as Fire Chief in Greenville for over 50 years, and it was his dream to one day build a museum in the community.

When the museum opens, it will have displays that depict the mining and logging history of the area dating back to the mid-1800s as well as local theater memorabilia from the mid-1900s. A collection of pictures and books give an overview of early life in the area.

Future plans include displays for local ranching and farming, Native American artifacts, local Chinese history, railroading, and the history of the Plumas National Forest.

The museum's rennovation has just been recently completed. Docents have created an historic walking tour of downtown Greenville, with brochures available in businesses and sign boards with pictures and descriptions on each historic building depicted in the brochure.
