A warning has gone out to motorists to beware of moose licking the salt off the side of their cars.
The alert, which has been issued by the government of Alberta, was prompted by cases of moose approaching and licking vehicles in Peter Lougheed Provincial Park.
Recommending a 'moose viewing distance' of 30 meters, officials have suggested using a car horn or remote door alarm to scare the creatures away.
"If there is no natural source of salt available they will find an alternate source, like the salt from the roads on vehicles," said Dr Doug Whiteside from Calgary Zoo.
The phenomenon has since become affectionately known as the 'Rocky Mountain car wash'.
