This anchor...

Is this anchor ok? I used it to rap/TR solo a bunch of routes today. I saw some other guy using it and thought it was the simplest, easiest anchor to build.



...and yes, that's a Moosejaw sweatshirt laid over the edge...

I later went on to build this anchor losing confidence in the first...

static rope is bomber, as long as its bomber condition wise, and that looks fine. im trying to conceptualize the second one, how was it made? dog earred figure eight i think, then you wrapped the tree twice and then...

It is a great static 11.6 line by Bluewater. With Anchor #2 I wrapped the tree twice, tied it just like a cordelette with the backup overhand on one strand. Then made a bight with 4 strands and overhanded it pulling the slack end over the bight before clipping opposing locking biners to the anchor. I like the 2nd better but it also takes longer to build.

That first one is text book. Bombzer. As long as the tree is solid.

The second one was a good experiment and would work fine but way to complicated with unnecessary shit cluttering it up.

Keep is simple.

If you're asking this kind of a question about an anchor I'd be a bit curious to see what kind of rig you're using for TR soloing?

Trango Cinch device to TR solo up and ATC Guide with auto-block for rapping down.

One thing worth mentioning I think....
Over time, a tree can be damaged or killed from being used as a climbing anchor. I don't mention this as an over the top tree-hugger, rather because damaging or killing trees are the types of impacts land managers can point to to close climbing areas. I'd also not like to see otherwise healthy trees get killed.

In desert areas, trees are particularly "valuable" resource. There aren't as many trees to begin with and it takes a lot longer to grow a mature tree than in wetter climates.
I'm not saying I've never anchored directly off a tree, I certainly have, many times, but there are ways to protect a tree trunk from excessive damage. One is by adding some bolts, others have in-situ webbing which seems to reduce rubbing on the bark some, I've added branches around the trunk before too. Takes a bit longer to set up the anchor, but does protect the trunk some.

Contradiction? yeah thats what I thought. Tree Hugger.

What are you trying to call me out on?? I called out my own contradiction in my post.
We'd love to hear your suggestions.

First one is better as the full wrap spreads the force around the whole tree.

Tight or Loose? Both safe for a person; being cinched MIGHT have a higher load capacity, but nothing significant for only body weight. Being loose is the only chance for the tree.. Being a Botany major, if you cinch the rope completely around the tree, this will eventually cut-off the vascular Phloem, resulting in the tree becoming decadent and less likely to hold a person. If putting high loads or just for the higher comforting-mental state, where the "cinched down" method will be used, then use a piece of carpet in between the rope and the tree to prevent this problem.

Plus, the carpet method will preserve the life of the anchor.

All you need is a no-knot knot.

That looks terrible for the tree, it rubs all the way around the tree and relies on cinching and friction to hold it.

use a tree further from the edge, that thing's barely attached. Doesn't matter how big it is but how well rooted in good soil - that thing looks ready to fall down.

+1 on Eli's comment.

When we were training for high angle rescue stuff @ UMaine, we did a lot of wrap three, pull two anchors w/ one inch webbing. Wrap the webbing around the tree three times, making sure to lay the webbing flat against the trunk. Then tie a water knot between the two ends of the webbing, and have the knot facing in line with the climb. Pull the other two loops out until your knot is sitting snugly against the bark. The benefit's are that as your load shifts, it doesn't shift the webbing, (which girdles trees over time). This all takes a bit more time, but protects the tree, and it's nice to top out and immediately see that your water knot is still peachy.

One way to protect against Eli's concern is to connect that tree to multiple trees. Any time you are dealing with serious forces (trail crew, rescue, really fat in-laws), pick your anchor and do a wrap three pull two as low as you can at the base. Then go to the next tree back, sling that low, and connect that to your primary/initial anchor tree up high (4-5' above your initial anchor). Tighten w/ a trucker's hitch (tie a slip knot and put the free end through the loop, gives you an instant 3x - 1x, not including added friction). Continue as many times as needed. Might seem silly to practice these skills, but they're amazing to have in your toolbox. I got several students over a flash-flooding river w/ a Tyrolean, and my biggest anchor tree was in loose sand, about 4" in diameter.

Like I said, time consuming, and DFL on the list generally, but I've been grateful several times for knowing how to do it.

You've got to be kidding?

I would think this has less impact on the tree than the standard 1" webbing looped around the tree. What else would you recommend? Note this is for a temporary anchor.

a small piece of carpeting works really well to pad trees. Or you can get an Edge protector from PMI if you want to spend money. What kind of knot are you using in the 2nd anchor? A better knot to use would be an alpine butterfly. No reason for the double figure 8 either.

Really all this discussion is stupid, there are 100 different ways to make an anchor that will be sufficient. The real question should be is it strong enough and the answer is yes. Is it the most simple? No. Will it kill the tree? Probably in time.

Climbing at devils lake and top roping there are a ton of trees people use for anchors. I had a small piece of carpet that worked great to protect the trees.

Actually, but not that it matters, the no knot is the strongest knot as it does not reduce the strength of the rope at all..

Read about it if you care to,

also more commonly referred to as a tensionless hitch if you want to use google.
