Took the half day tour led by Captain Ron. He was a walking and driving encyclopedia of knowledge about plant species, Native American culture, the geology that formed the region, the forces that underlie the power of earthquakes, the movement of the tectonic plates, etc. We also drove near, albeit not close enough, to the Salton Sea and ended the tour in Mecca at the Oasis Date Farm and enjoyed date shakes. Captain Ron, was engaging, interesting, thoughtful and helpful in every way. Ask for him when you take this tour!
