Allergic to Metal Top Rope Anchor

Allergic to Metal Top Rope Anchor, witnessed in The Gunks.

Alex Fox found this little gem when climbing in The Gunks a few weeks ago. “Allergic to Metal” is his name, due to the fact that, well, there is nary a carabiner or nut or cam other piece of metal anywhere to be seen. I’ve certainly seen worse anchors, but this is pretty Jive-Ass just the same. 

Apparently the yellow cord going off-camera is tied to a tree with some exotic knot Alex couldn’t identify. “[I]t was backed up with a double overhand,” he added, “so was likely fairly secure.” All fine and well I suppose. But the stuff in the shot? Yeah. That’s Jive-Ass gold! Here are the issues Alex was able to enumerate himself:

1) “The webbing is tied around a completely detached boulder.” In other words, a classic Wiley Coyote set up. It’s a pretty big rock, mind you. But it’s not really that big!

2) There is some “hot nylon-on-nylon action” (my words being quoted by the way!) where cord meets webbing in a girth-hitch. Why, oh why not just connect the pieces of cord with a carabiner? We know what can happen when you connect soft goods together with a girth hitch. This happens (note the paragraph titled “Cyclic”).

3) Then there is a dyneema sling, which has a melting point of about 130 to 136 °C (266 to 277 °F), rather precariously girth hitched around another rock. 

4) Finally, and this is the clincher, Alex notes that both the nylon and dyneema webbing have a few random overhand knots tied in them, which, as Alex eloquently puts it, “didn’t appear to serve any purpose aside from weakening its overall strength.”
