 As its name suggests, it contains a wealth of pictographs, including one that has been identified with the Hotcąk spirit Red Horn (Wears Faces on His Ears).Other pictographs in Picture Cave have been dated from about 915 AD to 1066 AD, although the age of the "Red Horn" pictograph has so far not been determined.It differs stylistically from the other pictographs in the cave and has a patina of silica which may suggest that it is older than the others.
