Beavers are full of surprises. Having felled this birch, a beaver has walked along the trunk, gnawed off the bark and jumped down onto the bank on the other side of the burn. At least that is what I suppose happened.
Beavers use stones a good deal in the course of building dams, but usually they are scattered around the structure. Here, in this small dam, you can see some stonework, which I thought unusual.
Fiona McLean of Stirling University has produced some interesting results from her sampling of the water in the Burnieshed Burn, but more of that for next time.
