My daughter and I left Whitney portal at 2:45 a m on June 10, 2018. Arrived at trail camp at about 7 a m. Started up chute and were considering turning back when four people slid down at over 30 mph completely out of control. They fell over 1,000 vertical feet. Screaming, bouncing, did not stop til bottom snow pack. Head injuries, broken bones, hypothermia, among injuries. Helicopters took between 5 and 8 hours. Worst accident I’ve ever witnessed. Please please do not let summit fever cloud your judgement on this stretch of the whitney trail. If anyone has an update of these climbers please post.
