It's a grey fox. They can climb trees!
Also,
you can swim in it... if you don't mind snapping turtles!
Speaking of which, a snapping turtle buried its eggs on the edge of a dirt parking lot on campus this morning. The professor got some pictures/video, and I'll try to get them from him.
Here's more of the "lake" (pond!), where i stay most nights to watch bats fly around above the surface.
I should have included something as a size reference. This is big, but not HUUUUUGE.
This is literally right across a small dirt parking lot from where I sleep. I can walk here in less than a minute, walking slowly.
