I climbed the beautiful South Couloir on Teakettle today with some guys from the Front Range. It was in great condition and we made good time. We followed the direct line up through all the narrow sections to the small summit block. It is mainly nice neve with a bit of hard ice in spots right now.
I've also been up Dallas Peak and Gilpin Peak by their steep couloir routes, and they are equally fantastic right now. Get it while you can.
Cheers, CC
