Calgary woman standing for a photo slipped into a B.C. river and

A Calgary woman has died after slipping into a river and being swept away in B.C.'s Kootenay National Park.

The RCMP say in a statement they were called Sunday and told a water rescue was underway in Marble Canyon.

Police say they learned that a 34-year-old woman was being photographed near the river when she lost her footing and fell into the water.

Cpl. Jesse O'Donaghey says the woman was pulled out of the water about a kilometre downstream and bystanders, including a medical professional, attempted resuscitation but she died at the scene.

A 29-year-old Calgary man who also tried to save the woman was pulled from the canyon with a high-angle rope rescue by a Parks Canada safety crew.

Police say the man was airlifted to a Calgary hospital and is being treated for non-life threatening injuries.
