Refinements on a fledgeling practice in the technique of DISTANT TREE-TO-TREE TRAVERSES.
This, as you say, Moss, has been going on for some time, variants of it, usually double-rope, DRT that is, TWO ropes. Set rope, cross over retrieve rope behind you, (or not) and continue on.
You do it entirely without a second rope, just a second shotline and that Jangle Bird Grapnel, this sort of traverse becomes an entirely different animal.
In Arboriculture, the traverses are often within the same canopy of a tree, like big oaks where you've gotta climb into 7 different sections of a huge canopy so you set your rope from one section to another (reset) then belay off the tail and ascend up the reset line. This is using one line, not necessarily single rope technique. Sometimes you belay out and ascend up in tight fashion, across, and stay high in the traverse, or just sloop down a ways and come back up. Good treemen who can do this stuff, do it and make a lot of dough, so it really benefits us to be the technicians they're paying us to be. Fun stuff.
But YOU, sir, have shown us how to do-tree-to-distant tree traverses. That rocks.
The only way I was seeing this done was fire the bag over desired target, let bag drop to the ground afar. Ground guy takes off the shotbag, clips on rope, climber retrieves single line, ground guy anchors the rope below, climber tensions applies ascension method and belays off his climbing line.
If you can control friction, modulating the friction device, using your feet, then you can put all your attention to the effort of the traverse out in front of you, which usually has a slope upward, as well as across.
But that's SRT out front, but the second rope letting you out is still a second rope in the system.
You,
are showing it
One
Single rope.
One lifeline, doing it all. At 50 some foot of span and without a second person helping. This one is a rare breed, this specific method.
You can be modest if you want, but without the foot slingshot, distances horizontal like that are just hardly possible. This is very unique and original.
I think that because of what is possible with this new piece of gear, + the refined method, this is uniquely outside the realm of anything we currently do in professional tree climbing.
And in the world of recreational tree climbing I would hope they recognize, although themselves maybe having done this method to whatever degree, that the bar in having done this has been raised to a new standard. Good job, Moss.
