I would get up there and saw those two cross / support boards about 3/4 of the way through.
battery dewalt sawzall will do it nicely, got a spare game cam to set as well.
Now that you've put it on the internet I probably wouldn't do that. Wardens do read this site and if some douche bag falls out and breaks his neck and they connect the dots you're going to be in a heap of [censored].
all I keep thinking is how much I hate junipers and how those trees might even make a bit of saw lumber and they would definitely make great corner post for a fence along with the limbs and tips making good fence post
or they would make good post and beams for a shed
I would be temped to cut the whole shooting match down and make something useful from it
just let the sawyer know there could be nails in the wood though
the wood for the stand if not salvageable would be good to get a nice fire going.....it is winter and cold out there
