We started the summit climb at around 10:30 PM. While waiting for other climbers to get ready, I pulled out my camera hoping to get a shot of Seattle nightline only to realize that the batteries were too low for pictures, somehow OK for video clip. I tucked it my chest pocket hoping to warm up the batteries. But unfortunately the whole ascent was very windy and quite cold. I didn't have any chance to take any picture until we descended to almost above the high camp.
