We planned on going in over Cottonwood Pass on Friday, but after an painfully cold night at Horseshoe Meadow, we changed our plans. We were able to snag some overnight permits to go up the Whitney trail and summited on Sunday 9/24. We camped at Outpost camp on the 23 & 24 and it was still below freezing.
Ice on the cable section, but not much else to speak of on the trail. In the morning hours we found some icy rocks on the creek crossing near outpost and some ice on the trail, but it was on a flat spot on the trail and passable.
