We summit-ed on Jun/08. It was pretty hot and had to remove two layers after the very first mile. Snow starts above the Trail camp. one person in our group took the chute to trail crest while the rest proceeded on the SB. From the rails section we needed to have micro spikes on . There were some Switchbacks which were very slippery and would definitely recommenced We wore the micro spikes all the way to the summit as there was some patches where it gives stability and also wore it on the way down till the rails on Switchbacks. One member in the group took the chute down trying to plunge step and slid with ice axe , he said it was a bad decision as the bottom part was very icy and he took 30 min more than us and made it without any issues. From trail camp there was no issues to whitney portal .
