Located in the heart of the Inland Empire, our group of Sierra Club resides and serves the communities of Riverside and Moreno Valley, California. Formerly known as the Moreno Valley Group, our name now is in reference to Box Springs Mountain, the highest peak between our two cities. Our group is one of many working within the San Gorgonio Chapter of Sierra Club. Use this link to get involved!
