Extreme depth: Explorers map out B.C. cave believed to be deepest in Canada
FERNIE, B.C. — A member of a team of explorers has reached a record depth in a cave near Fernie, B.C., that is believed to be the deepest in Canada.
The cave has so far been measured at 5.3 kilometres in length and 670 metres deep — more than 200 storeys below the ground.
Project leader Jeremy Bruns puts that in perspective by pointing out that the CN Tower in Toronto is just over 550 metres tall.
The Calgary-led group began exploring the Mount Bisaro plateau in 2012 and has done roughly 10 expeditions.
