2010 marks the end of the first decade of the 21st century, and a milestone for the Southern Tuolumne County Historical Society (STCHS). It was 10 years ago that STCHS completed the construction of the Museum & Library building. We have maintained the building and operated the museum ever since.

Our mission is to preserve, protect and present the unique history of the Southern Tuolumne County area for public benefit. If you are not already a member of the Southern Tuolumne County Historical Society, please consider joining us. Memberships are as little as $20.00 per year. Your support is deeply appreciated. Stop by the museum and pick up a membership form.

The Groveland Yosemite Gateway Museum has become a Museum Partner with Use as your portal for online shopping, and you may designate Groveland Yosemite Gateway Museum to receive a donation.

The museum store sells a wide variety of educational items, historical books and documents, as well as flora and fauna identification books. Many are written and autographed by local authors. The store features local human history books and natural history books. Also found at the store are gifts for young and adult alike. DVDs and videos telling of the features and delights of Yosemite are also available.
