A few pictures from today. This is the lodge that I'm starting at. If you look carefully you can see my blue and yellow work glove hanging on a branch on top of the lodge. It puts it into perspective as to how huge that thing is.
TFNG, using the tip of the chainsaw bar instead of the auger was a much better idea, thanks. The main run where the branch is sticking out of the ice in the middle of the picture was easy to find, the ax when through just tapping on the ice, but the slough is really shallow and there's only about 1' of water under the ice right out to the shovel. I'm not really sure what I'm looking for but I found deeper water to the right and left of the feed bed. I'll have a better look when I put a couple of feedpoles in.
Breather hole on the edge of the reeds on the main run to and from the feed bed.
