Long day! Took almost as long getting down as getting up. Scramble was not bad at all past the glacier. In fact it was barely Class 2 until the very top 5 feet. The true summit has a lot of exposure. There is nothing more impressive than standing on top looking 3400 feet down at Colchuck Lake which appears directly below you.
The glacier can be a bit steeper if you hang toward the left side. We were camped at Little A above Crystal Lake, and spent the morning hiking over to the Prussik Peak area before heading up Dragontail. This allowed the glacier to soften a bit for some nice steps.
