Beaver Dam

I was walking on a trail in a nature preserve in south Jersey the other day when I came to this sign. Closed by beaver you say?

There was an orange warning finger, so I was definitely going that way.

I passed this. Beavers?

Then I passed this. Can't look any more beaver-gnawed than this.

Then the path ended in a pool and a beaver lodge. How cool is that?

And to the right -- a beaver dam!

A big beaver dam. See it curling away like an S?

And here's the pond that the dam contains. Good job, beavers. I thought I heard a tail slap so maybe a beaver saw me, but I did not see it. I'll be back to check on progress here later, so hopefully I'll get a beaver to pose for me then.
