The route is the seam-system on the glassy North face on the main rock at Supremacy. It is low angle, but requires good face and slab technique alike. The climb goes up the centermost crack system and left and right lie harder variations that eventaully all join and move up and left to the 5.7 arete.
There some pro, primarily small stoppers, but the crack is flaring and discontinuous. You can work in one or two good ones on the main slab, then more as the climbing joins the North arete to the left. On the otherhand, it is possible to set a TR with a ton of webbing and gear, although a TR fall results in a big swing, potentially into the tree behind the route.
