What's underneath it? Anything of value?
It's hard to get a perspective from the photos. It looks like the root ball of the first tree is still in the ground for the most part. It most of had some strong winds behind it besides the weight of the tree to bend the other tree like that. Now that things have settled down, I think I would shoot a line over it and see how it reacts to me pulling on it some. If wedged in there pretty good, you could access it throu another tree or walk up the leaner and secure it to the tree its leaning on and anything else you can rope it to so its more secure. Then start by lightening it up, cutting everything on the other side of where its secured, removing as much weight as possible. Then see what it does.
This is just speculation Ace, it easy being a keyboard climber, but if you then ran some bull-line from where you had the two trees secure down to the ground at an angle and back some, so it would turn it as it came down, (you might have to remove another tree or two) then wrap the tree that is under tension with some strapping and and carefully cut it. I don't know if this is possible with out being crushed or not from the picture
but my thinking is it wasn't just the weight of the tree that put all that strain on the bending tree, but had help from strong winds, Removing as much weight as you could and if it still has roots in the ground the forces are minimized some.
Again if the over hang weight was removed(big if)you'd might be able to winch it to the side so the big tree would slide down the one its leaning on as you side cut it.(setting a pulley up high in a other tree.)
That bent tree could be like a mouse trap ready to spring, doing all kinds of nasty things, but those forces shouldn't be as strong at the base.
Without being there to see and feel all the veritables involved its almost impossible to come up with a safe solution, but if there isn't anything that can't be sacrificed or moved under it , there are options. If there are valuable targets under it, a crane maybe the only way. Snags are unpredictable and dangerous. I'd be tempted to just start cutting the big tree slowly at the base and see if it would all come crashing down.
Them are the kind of trees that kill you, if your not comfortable, don't do it. And take any advice you get from the rest of us with a grain of salt, you have to be there and see what's up to be able to come up with a safe method of removal. Fly me out there and feed me, I'll help get it down with you.:msp_biggrin:
