Ministry of Foreign Affairs environment The two women were reportedly hiking with their off-leash dogs near Landslide Lake when the incident occurred.
The group encountered the big cat, which attacked one of the dogs and bit a woman.
The hikers used bear spray to repel the mountain lion and were removed from the area by helicopter.
The woman was taken to hospital for treatment, and both she and the dog are expected to recover.
The BC Conservation Officer Service determined the attack was defensive in nature and no further action is planned against the mountain lion.
BC Parks has since posted signs warning of cougar activity in the area and closed the Elk River Trail for safety reasons.
