Bowed out Aspen

In the recent storm a tall lop sided aspen (Populus tremula) tree fell down on the riverside parks in Hoveton. The tree had surpassed its natural height for marshland trees. "There are still about 6 more still growing in the same location and doing well. A fast growing tree. No more than 40 years old." ~ Steve Moore

Curiously, the fine looking aspen was growing out of the silted remains of a dried up dyke, going from the River Bure towards Station Road. This is one of several lost water courses dug usually by hand and utilised by reed lighter boats and the like for transporting stuff. The channels were filled in over the last 50 years or so in the Hoveton ~ Wroxham area, as the riverside turned ever more from an agricultural workplace to a leisurely destination. 

Can you count how many rings there are on the hewn trunk to tell the age of the tree?
