Empire Mine SHP

Empire Mine State Historic Park is the site of one of the oldest, largest, deepest, longest and richest gold mines in California. The park is in Grass Valley at 10791 East Empire Street. In existence for more than 100 years, the mine produced 5.6 million ounces of gold before it closed in 1956. (5.6 million ounces of gold is equivalent to a box seven feet long, seven feet high, and seven feet deep filled with gold.) The park contains many of the mine’s buildings, the owner’s home and restored gardens, as well as the entrance to 367 miles (the distance, as the crow flies, from Grass Valley to Magic Mountain) of abandoned and flooded mine shafts. The park consists of forested backcountry and eight miles of trails - including easy hikes (for hiking, mountain biking and horseback riding) - in the park.

Fuel Reduction Project at Empire Mine to Reduce Wildfire Risk

A fuel reduction project will begin Thursday, October 10 at Empire Mine State Park.
During this time in the interest of public safety, trails on Union Hill will be subject to intermittent closure in areas where heavy machinery will be operating.
 
The Sierra District of California State Parks’ effort is designed to reduce the risk and severity of wildfire in the park. This project is scheduled to be active through October and November and finish in December 2013.  A large mobile masticator will be used to chip small trees and brush within the project area. There will be 100-foot undisturbed buffers on select trails and a 200-foot buffer on the park boundary.

 â€œWe hope to reduce the fuel load and provide defensible space to the park property boundary, and to improve the health of mixed conifer and oak forests to reduce the risk of catastrophic a wildfire,” Sector Superintendent Matt Green said.

Work will be performed by Sierra Nevada Forestry Services of Yuba City, CA.  The chipped material will be left on site.  This project was made possible by a Healthy Forests grant from the Sierra Nevada Conservancy.

For questions or additional information about the project, contact Sierra District Forester Rich Adams at (530) 581-5746.

The project had been scheduled for later this fall but was moved up when early rains made conditions favorable. We would like to ask for your patience and cooperation as we conduct this project. Thank you for your continued support of California State Parks!

Guided Tours and Living History Presentations

Guided tours and audio-visual presentations are offered throughout the day at various times.

The Secret Room

To keep track of the mine's 367 underground workings, a place called "The Secret Room" (named for its blacked-out windows) was built. In it, the entire room was filled with a scale model of the mine's below the surface workings. Few people knew the room existed while the mine was in operation. Today, visitors to the park can see it in the Visitor Center. The model represents five square miles of underground workings. When the visitors go down the actual shaft in the park, they have journeyed only "one inch" on the model. Anything past "two inches" on the model is underwater in the actual mine.
