In the morning, we asked the students (those that felt comfortable with their presentation) if they would like to go for a walk at the Beaver Pond Trail.
Towards the middle section of the trail, we actually stumbled upon a beaver (Castor canadensis) on the trail gnawing on a low branch. Just a few moments ago before seeing the beaver, the students were talking about a man-killing beaver (news here), and so the students were startled (to say the least) when they saw the actual animal. Long story short, the beaver paid no attention to the shrieking students and left, while the only photo I could get was above.
