ericp, I just copied those pictures from Instagram. I don't know the details of their trip. ...ok, more info: christinec_097 was with "xerorisk", shows some of the same pics, and a little more info. One of her pictures shows the summit hut, and the caption reads: "Early morning at the top of Mt Whitney. This cabin kept us alive at 14508 elevation"
Not sure if it was planned or not, but they spent the night ON the summit! I don't think they carried overnight gear.
