I've climbed both of the lines you've highlighted here. The Beginning trends right through the dihedral and the variation stays left. We climbed left first and figured it certainly wasn't 5.7 and then climbed the dihedral and that felt right on.
I can see that, even with boots, gloves, snow and ice the variation we did seemed easier than 5.7. I imagine in fair conditions it would go easier. The dihedral looked to be a good challenge at 5.7 though, I'll wait until I can wear my climbing shoes to pop into it.
I'm not saying The Beginning is not 5.7. The Beginning (if you climb the dihedral to the right of the blocky ledges) is certainly 5.7. However, the blocky ledges to the left of the dihedral are not 5.7- more like 5.5.
Climbing The Beginning in Feb 2011. We weren't sure if the route was supposed to stay in the dihedral (dashed white line) or go slightly left (solid white line). There was a fair bit of snow and ice, so we climbed it in boots and gloves and went left of the dihedral for a 5.5 variation?
