Remote video cameras in Glacier National Park are capturing bears marking trees. LiveScience did a funny treatment of the video, editing several captures together and cleverly adding music to make it entertaining.

Not surprisingly, we didn’t see anything like this when we visited the park, but that’s to be expected when you pretty much stick to the main road through the park–along with every other visitor–so there was probably no chance of seeing relatively shy animals like this.

The raw (boring) video footage from the USGS Northern Divide Grizzly Bear Project can be seen here.

Note: The current projected opening date of the Going-To-The-Sun Road this year is June 13.
