| The good news, this anchor was never even loaded, the knot didn't tighten. The bad news, run way up that little tree, it would have levered the tree severely. |

| The climbing rope was rigged for rope soloing. It is close to a tensionless anchor, so I guess the half hitches don't matter much. The guy climbing in work boots was using a single Jumar-type ascender, which would be lucky to not sever the rope if he fell. Must be the heat. |
Pic #1. Strive to find a tree at least 12 inches in diameter.
ReplyDeleteNEVER anchor to a tree less 6 inches in diameter (some say 8).
Tie your anchor as low as possible on the tree.
Pic #2. Self Belay systems (thats whats I think you are referring too) need to be redundant.
AND need to follow all the same rules like 6-8 winds with a (loose ended) knot connected to a locking carabiners for a tentionless anchor.
There needs to be two fixed ropes with two independent and two different auto-locking devices (I recommend the Petzl system.. See links below and live longer).
