This is a wire bait mound.  A barbed wire fence corals a mount of debris which attracts bears.  The wire snags the bear hair which is then collected by scientists for DNA analysis.  The mound is scented with rotten blood and
fish.

This is hair from a grizzly bear snagged on the barbed wire fence that surrounds the bait mount.  Hair samples are used to identify individual bears through DNA analysis.
