Javier,
BTW, if you are looking for a challenge, join me on the Whitney-Russell traverse in October!
We will climb MR, downclimb North slope, go over Whitney-Carillon saddle, climb South Face of Russell, downclimb East Ridge, bag Carillon on the way out and call it a day.
We are planning a Winter ascent of Williamson via George Creek this December as well
This should be quite a suffering
