We planned on about 30-45 min a pitch for 20-24 pitches. This seemed logical.
We set up midday thursday for the Plan above chamonix and set our bivy. After some afternoon cragging, we returned to find our bivy inundated by the afternoon snow melt. Sweet. We set the alarm for 4am the next morning and headed up the Nantillion Glacier in our tennis shoes and ski poles after eating some chili-con-carne/Ratatouille (highly recommended).
Tom decided to spice things up so he left the topo in a crevasse somewhere. We had only this mental image:

Anyway back to climbing:
Tom leading some easy but nice slab traverse.

Tom seconding after an easy crack system that reminded me of Diedre at Squamish.

Tom on a wicked corner.

The one pitch we could simul climb consisted of easy but somewhat loose rock before transitioning onto the upper headwall.

The granite on the upper head wall was immaculate. Incredible featured faces leading to finger crack traverses, overhanging corners and hand cracks.

Golden alpine granite, split by a moderate off-width (5.9+ish)

Tom at the top-out right before the weather started to go tres mauvais.

Wow time flies when you're having fun...it was 6pm or so when we topped out. No problem, just a few (18) rappels to get down.
Just as we began our first rappel a massive storm arrived bringing torrential rain, thick fog, sleet, snow, and hail to our already hasty descent. As my fingers froze, I foolishy fumbled my belay device into the abyss. Relying on a Munter abseil the route, I nicely mangled Tom's new ropes and twisted them up into tangle after tangle. Freezing and less-than-stoked we made our long, long, long descent to our bivy in 8 hours in the complete dark. Who said alpine climbing had to be fun?
After we finally reached the glacier, we had a nice glissade session in our tennis shoes on white glacier ice and witnessed/heard some large rock falls onto the Natillion Glacier. Reassuring.
Exhausted, shivering, and starving, we were excited to return to our soaked sleeping bags and try and make our way back to Chamonix which involved 2-3 hours of downhill trail, and about 4k vertical feet. We decided to bivy at the camp because it would be light in less than 3 hours. In my sleeping bag I placed a space blanket which did slightly less than nothing to keep me warm.
Other than that, things are going great. Today we ate combined 100,000 calories in pastries and I had Tom power wash me in his backyard because I needed more punishment. I think I'm going to spend the next few days eating bananas and sitting by the pool. Applying sunscreen. Lots of it.
