Phantom's Crag is a low but impressive peak that lies to the right as one enters Devil's Gap while travelling west. The route in the valley below Phanton Crag passes through the front ranges of the Canadian Rockies. It is now occupied by Lake Minnewanka but was originally established by the ancestral Bow River. It is thought that the huge volumes of glacial till blocked the valley as the last iceage ended some ten thousand years ago, forcing the river to follow and deepen a new channel from the area of Banff Townsite. Devil's Gap was regularly used as a path into the mountains by the natives, in fact one of the oldest archeological sites in the area is near the western end of Lake Minnewanka. According to Gillean Daffern, fierce skirmishes between the Blackfoot and Kootenai Indians were fought in the area and are the source of a legend telling of a ghost seen going up and down the Ghost River, picking up the skulls of the dead. This may be the source of the names related to ghosts and phantoms. Regarding the peak, it may just have been a hazy day when the name was first used.
