Did you know that we had large Ice Age mammals in southern Arizona? At the Murray Springs archeological site along the San Pedro River near Sierra Vista we will learn about the Pleistocene megafauna which roamed the savannahs. Alongside these mammals lived the Clovis people, great hunters, which we know from their fluted projectile points. For lunch we will stop at the Holy Trinity Monastery. Our last activity will be combing the St. David Formation for gypsum crystals. Transportation included.
