This is … a beaver dam?  I think?  I spotted it in the Roanoke River the other night … there were furballs of some kind down there, and I saw an enormous heron swoop down to join them. I shot video, but it was too dark to share.

Is it a beaver dam?  Feel free to correct me if I’m wrong.  I won’t be embarrassed.  You know I am a native New Yorker, and have no acumen for Virginia fauna.  Maybe it’s a muskrat maze or ferret fortress or a nutria superstructure.  You tell me.
