Update (December 7, 2020): California has issued a Regional Stay at Home Order to stop the surge of COVID-19 cases and prevent a strain on the health care system. This action will help protect critical care for patients. While the order includes the closure of campground sites in impacted regions, the state also recognizes that mental health is physical health. As such, day use outdoor areas of park units currently open to the public will remain open. Members of the same household are encouraged to stay local and recreate responsibly in the outdoors. Please take the time to read the information contained on this webpage to find out what is open and closed, and the COVID-19 guidelines for this park unit.

    • Off-highway Vehicle Recreation: Do not ride next to others or pull up next to someone else as it could put you in close proximity to others. Stage 10 feet or more from each other during unloading and loading.
  • Keep Clean – Be prepared. Not all restrooms are open to the public. in some cases, restrooms will be temporarily closed to keep up with cleaning schedules. Bring soap/hand sanitizer. Please pack out all trash. Park units are experiencing heavy use and you can help alleviate the impact on park facilities.
  • Stay Covered – The state requires you wear a face covering when you cannot maintain physical distancing of six feet or more. Individuals must have a face covering with them at all times.

Statewide, California State Parks continues to work with locals on a phased and regionally driven approach to increase access to state park units where compliance with state and local public health ordinances can be achieved. However, the situation remains fluid and park operations can change at any time. The need for Californians to slow the spread of COVID-19 in the outdoors remains critical.

“There’s gold in the hills of California!”  These words echoed around the world in 1848 and started a mass migration to the wilderness of interior California.  Gold seekers trekked from every part of the world and every walk of life to sift the streams for gold.  Mining companies brought machines to the mountains and turned camps into boomtowns as they blasted and dug deep into the earth to follow the gold bearing veins. 

There is still gold in the foothills of the Sierra Nevada, at the California State Mining and Mineral Museum, in historic Mariposa.  This is where explorers John C. Fremont and Kit Carson found the rich Mariposa Vein and opened the first mill to crush ore and extract gold in California.  You are invited to discover for yourself California’s mineral wealth, colorful history and geologic diversity as you view the official mineral collection of the state of California.  The collection, which began in 1880, contains over 13,000 objects including mining artifacts, rare specimens of crystalline gold in its many forms, as well as beautiful gem and mineral specimens from California and around the world.  The collection was moved to Mariposa in 1983 after residing in San Francisco, for over 100 years.  The museum became a state park in 1999.

We are proud to display the Fricot “Nugget”, a rare and beautiful specimen of crystallized gold discovered in the American River in 1864.  This spectacular 13.8-pound. specimen is the largest remaining intact mass of crystalline gold from 19th century California, when these finds were more common but usually were simply melted down.  You can also take a trip back in time as you walk through our mine tunnel and see how gold was mined in the mid-1800s, when California was a wilderness, being transformed by rapid development. Our assay office and working scale model of a stamp mill will help you discover how gold was found and extracted from the rocks.

The museum is dedicated to helping families and students learn about the importance of mining and minerals to our history, our environment, and our future.  We offer free activities for children and youth groups, including our Junior Ranger Program.  We also provide school tours relating to geology, rocks and minerals, the gold rush, and mining history to hundreds of students each year. We encourage teachers and youth groups to call about our free, hands on, fun and educational programs, which also support California state curriculum standards.  Custom tours can also be arranged for special groups.

The museum even sponsors an annual gem and mineral show each spring featuring exhibits, speakers, food, educational children’s activities, and dealers of beautiful mineral specimens and lapidary work from around the world.  Call the museum for dates and times.  We also feature special mineral related activities and crafts during the annual Mariposa County Fair, over Labor Day weekend.  Our museum shop offers a wide variety of jewelry, mineral art, and mineral specimens as well as many books about rocks, minerals, prospecting, mining, and California history. 

A visit to the California State Mining and Mineral Museum offers you the chance to explore the variety of California’s mineral wealth, view breathtaking gems and minerals from around the world, and to experience a bit of California’s exciting mining history.  We have a number of rotating displays so there is something new to see each time you visit.  This museum is a must see stop on any trip through the Mother Lode gold country or to nearby Yosemite National Park.

Educators can call the museum for information on curriculum based educational programs for Grades 1 - 12 and college level.
