Are you expecting any different answers than on mountain project? You got some great info over there.

I think my nerves were getting to the best of me, I think this anchor was overkill.

What do you think?
The single cordelette tied off was a sufficient anchor by itself, wasn't it?

That's a sturdy looking tree you chose, and it's good to attach your gear as close to the ground as possible. It's too bad you didn't show us what you have below the picture. I guess that's the edge of the cliff, and also I guess that you're hanging your climbing rope through a couple of biners, hanging over the cliff ? ?? ???

You've built two anchors on that tree, for redundancy. I'd say that each one has plenty of load-carrying capability. But they're both on the same tree. So if you guys manage to tear the tree out by its roots, both your anchors will go with it, and your redundant gear will both fly over the edge, and your rope with them.

So here's what you should do:
Go ahead and sling the tree. Use that sewn sling just like you have it, but set it at the bottom.
Then find a different anchor, for your cordalette. It will probably be a tree or rock, further up the hill. So use that cord.
Get another couple of slings, enough to hang your pair of lockers over the edge, for your top-rope.
Equalize them somehow. You don't have to be perfect, and the two anchors don't have to connect to each other.

What's that pink blob at the bottom of the picture? It looks like a girls mittens. That's another good idea!

I went to climbing school at a cliff with easy access to the top of the cliff, for top-ropes.
Our rule was to always set two anchors, each one strong enough, both totally independent from each other. As beginners, this rule saved our butts sometimes.

Jesus, that thing's huge! ...
I'd certainly rather see that then some of the crap I've encountered over the years.

Noob question incoming (so watch out!) ...

How is the webbing and the red gate locking biner actually backing up this anchor? If the rope slung around the base of the tree fails it is just going to slip right through that locking biner.

Maybe it's just the angle of the picture, maybe I'm not recognizing the knot. What am I missing?

Do we have a scenario here where two working ends are coming over the top of the biner and two working ends are coming under the biner? In which case if the section wrapped around the tree fail, the stopper knot will load the webbing via the locking biner?
Thanks in advance. Like I said, n00b ??? incoming.

Yes, the bolded portion is correct, the knot has 4 strands going into it, the biner is clpped with 2 of the 4 strands going over it, and 2 of the 4 going under it.

It's still pointless though because the cord is already doubled around the tree and therefor backing itself up (i.e. you could cut one of the strands going around the tree and the anchor wouldn't fail).

Uhhh... no offense, but you will find this answer to be funny once you have been climbing for a few years.

I don't know shit about this stuff, so take what I'm saying with a grain of salt.

But from what I can see it's not necessarily about overkill, rather than pointlessness. The possibility of something going wrong with just the single cordelette was more likely to be the tree getting pulled out than the cordelette undoing, or snapping, or whatever. So wouldn't it make more sense to find another anchor point as a back up, rather than backing up on the same tree? It just seems like a waste of time to do what you'e done.

But like I said, I know next to nothing on these matters...
