Logs and branches from several trees felled and then cut up. I'm working round the edge, felling the trees into the centre of the Glade or into the space left by the previous felling. The aim is to avoid felled trees getting tangled ("hung up") in standing trees, as the danger is the hung up tree falls on you when you want to fell the other one. If you don't clear up as go along, you end up with a giant version of the pick up sticks game. But since you have a chainsaw, that's not a big problem ...
