Bring rope and rappel gear. There's a chance that there will be enough snow to down-climb the crux, but don't take that chance, that's how accidents happen.
Dead Elk Couloir starts off on a 45+ degree slope in a no-fall zone, watch your slough due to the exposed nature of the top part of this route. This goes for only a couple hundred feet before the walls choke at small cliff or down-climb. We had heard that there were rappel anchors here in the past, however we didn't find any and ended up using a rock in the middle of the down-climb as a rappel anchor. (If anyone feels like putting a new anchor in at this crux, that would be very appreciated).
After the rappel, you can expect to enjoy about a thousand feet of beautiful, technical couloir skiing before opening up on Tyndall Glacier
next to the mouth of Dragontail Couloir
