Image of American mink

Description:

A slender, dark brown mammal with a narrow snout (unlike the more blunt face of a muskrat or beaver) and a white chin. I would estimate that it was about 18 inches long from snout to tail tip. It was swimming in Lake Frederick (Frederick County, VA), and it climbed out of the water at the dam. I got photographs of it swimming (the white chin is evident in that photo), and on the dam.
