There are a couple I walk by every week, both pretty large.

I’ve tagged them natural=beaver_dam ‘cos I found it in some discussion on the wiki somewhere.

Considering so much of Canada is shaped by beaver dams, I think they should get more respect.

(the location for this diary entry is near one of the beaver dams. It was not actually written while near it. If it had been, the beavers would have done their irritated tail-slapping dive to scare me away. It sounds like someone throwing a large rock into deep water.)
