We next drove to Mokelumne Hill, which is off of Highway 49. There are old buildings and ruins, and the buildings were built of light brown rhyolite tuff from local tuff quarries. The area has a lot of vegetation; we were unable to find the quarries noted in the guidebook. We found outcroppings of the rhyolite tuff stone near the Mokelumne Cemetery.
