Dream Cave

Dream Cave (sometimes called Dream Hole or Dream Mine) is a natural limestone cavern located near Wirksworth and Hopton in Derbyshire, England. It was discovered by lead miners in 1822 and was found to contain the almost complete skeletal remains of a woolly rhinoceros and other large mammal bones. These remains were acquired by the geologist William Buckland and are now housed in Oxford Museum.
