A survivor of a rockfall last week in Banff National Park says his 33-year-old roommate Hamza Benhilal, who didn't make it out alive from under the rubble, warned him of the falling rocks and saved his life. Khaled Elgamal, 28, of Surrey, B.C., remembered his friend’s last moments at Bow Glacier Falls, about 200 kilometres northwest of Calgary.
