Some other ways to make the Crochues Traverse longer:
* Do a higher percentage roped, lower percentage unroped. (It has been done many times with no rope, but no doubt many more times roped for the entire distance).
* Continue along the ridge beyond the Aig Crochues, going downward toward the next col (? Col des Dards?) then abseil on the E side down to the glacier (if it's still there?), before descending to Refuge Lac Blanc.
* Or continue below the E side of the ridge to the E side of the Aiguille Belvedere, and climb the Belvedere (but I've heard that the rock on its S side is bad, so check about rather going around to the E or NE or N side before finishing up to the summit. Then descending the same way back to the glacier.
. . . (because continuing the traverse down the N side of the Aig Belvedere is a rather different kind of undertaking) .
I'm a big fan of the Crochues traverse.
