n The Jewel Cave Adventure Herb and Jan Conn trace the early history of Jewel Cave, discovered around 1900, and describe exploration before 1959. They tell, with humor, of the day the little cave took possession of them, and with quiet excitement, of how that day in Jewel Cave led to nearly two decades of dedicated exploration and mapping. During their exploration, the cave grew to over 50 miles of complex, three-dimensional maze.
