Sublime Corn Turns on the Thayer HeadwallEvery year I write down a list of goals to accomplish in the outdoors.
The past two years, climbing and skiing from the top of the Thayer
Glacier Headwall on North Sister has ranked among the top five on the
list. Last season, I was unable to check off the Thayer Headwall, but
not for a lack of trying. I skied into the east face of North Sister
three separate times, only to be denied access to the mountain's upper
reaches due to avalanche conditions. One memorable occasion, after
deciding the avalanche conditions were too dangerous, I witnessed two
big slides tumbling down the east face while eating lunch a safe
distance away.
The Thayer Glacier Headwall is a very natural and
aesthetic climbing route. Looking out my window at North Sister, I have
scanned the face with binoculars hundreds of times eyeing the potential
for ski mountaineering. The route begins just above a tarn sitting at
the base of the east face. It climbs the lower portion of an hourglass
through a constriction, pinching down to only a couple ski lengths
wide, before reopening. Instead of continuing up the upper hourglass,
the route bends to the right aiming directly toward the summit.
