Today we went to the Native American Grinding Rock and Sutter's Mine. When we were at the Native American Grinding Rock we saw a lot of Petroglyphs on the main grinding rock (petro-rock glyph-writing).
There was also a museum shaped like an Native American Round house. There was also an hour long nature trail that we didn't go on because we didn't have time. At Sutter's Mine got some rocks, my brother cracked a geod, and my sister and I went into the mine and went down about 1200 feet (I think).
