In this exhilarating work, Barbara Hurd explores some of the most extraordinary places on earth, from sacred caves in India to secret caves in Arizona. With passionately informed prose, Hurd makes these strange dark spaces -- with their stalactites and blind cave fish and ancient galleries of white flowstone -- come to light, illuminating the natural history and spiritual territory of caves as powerfully as Kathleen Norris portrayed the Dakotas. Entering the Stone provides an awe-inducing tour through a fragile and beautiful subterranean world.
