Yeah I think it is a mink as well. We have a fisher living in a rock wall across the street. Has a different face and definitely a forest animal as opposed to a mink that is a water animal.

Very bulky and muscular, for digging and ripping open trees.
Mink
More sleek body for water use.
Oh yeah I edited this to compliment the picture as well. Awesome shot. I always love your pics. Someday i wanna grow up to take pics like those you take. I don't know how you do it. I never have my camera at the right time or angle or light....argh. I should take a course. But Like Jonas said "Nice Picture".
