If you have visit the park grounds of the CA State Indian Museum and Sutter’s Fort State Historic Park lately, you might have noticed some weird growths on oak tree branches and leaves. Those are oak galls and some are referred to as oak apples! In this video, Theresa discusses oak galls that you can find on our valley oak trees, how the galls are formed from an oak gall wasp, and traditional Native uses of galls. Don’t worry, the galls don’t harm the tree but please don’t try to eat the oak apples. You can learn more about oak galls, oak trees, and acorns on Saturday, October 18th, at our annual Acorn Day! This is a fun day of demonstrations, arts & crafts, educational booths, guided tours of the park, and to learn all about the process of turning acorns into food.

There is a separate charge to visit the museum and Sutter’s Fort where there will be interpretive stations around the Fort as well this day. ...
