Marcus Reynerson explains river otter scent marking

While teaching on the Snohomish River in Western Washington, Marcus discovered the tracks and sign of some recent scent marking activity of a river otter.

A prominent sandy location above a body of water such as this is a typical location for river otters to scent mark.

Scent marking stations include scratch marks, scat and other secretions, often deposited on vegetation.
