Great TR Ryan!
Dan and I made two double rope raps down the
South side. We found a decent horn off the
snow field, and then a strong enough bush for
the second anchor. We were still short by
about 50' from safer terrain, but couldn't
find anything to rap off. Dan cleared out
more than a feet of snow to find ice, but
it was not thick enough to make a V-thread.
So we downclimbed that portion, which
included an interesting step of what I
thought was thin WI2 (about 10 ft long).
We then walked over the East ridge that
connects Argonaut and Colchuck. On our
way up, we had noticed a couloir coming
off from right in the middle of the
ridge. It was not easy to spot that when
looking from above though. There were
some cornices jutting over the edge and
we had to be careful not to go too far
looking for the descent couloir.
After wandering a bit, Dan climbed up to
a vantage point on the ridge and spotted
the exit to the couloir. This couloir
was still in the shade and hence the crust
was decently hard at places. It was only
around 35 degrees steep, and we plunged
our way down to meet Ryan at the bottom
of the couloir.
We thought we heard some voices on Sunday
afternoon when we were packing out (at
around 2:30 pm). Dan shouted a big Howdy,
but didn't get any response.
I was pretty beat by the end of the day.
It took me more than two hours to walk out
the road from the trailhead, and 2 Red Bulls,
1 180, 1 Monster, and 1 cup of coffee to
drive back home

PS: I'll post some pics later this evening. Patience you must have
