Named a Provincial Historic Site in 1986, Rat's Nest Cave near Canmore, Alberta, extends for approximately 4 km beneath Grotto Mountain. This new cave guide not only examines the natural history of this fascinating system of subterranean passageways, but also explores 2000-3000 years of human occupation.
