A 40-year-old Quebec woman is dead following a climbing accident near Lake O'Hara in Yoho National Park.
Wardens say the incident happened around 7:30 p.m. Sunday.
The woman and her climbing partner were on a steep slope below the Abbot Pass hut when a football-sized rock bounced down the escarpment and hit the victim in the head.
A helicopter later took her directly to the coroner's office in Golden.
Wardens say the woman was not wearing a helmet.
