An avid mountain climber and outdoorsman from Calgary has died in a climbing accident in Mount Robson Park.

Rick Collier is a former Mount Royal University literature professor, who ran for the provincial NDP in the last election. He was also a social justice and environmental activist.

Earlier this week, Collier was leading a party of four up Mount Geikie in B.C., when a rock face gave way, causing Collier and the others to fall.

The B.C. Coroner's office says the 71-year-old died within minutes.

The other members of the party were rescued. Two of them were injured.
