July 24
Last night was a grind. We drove into Glennallen at 10:00 PM. All of the
motels were full. We had no option but to continue driving. The next town
was Palmer - 150 miles away. We arrived at Palmer and checked into a dive
of a motel at 2:00 AM. Beds! A shower! It had been a couple of weeks
since we had experienced these niceties. I conked out on the floor of one
of the rooms before I managed to peal off my pants.
When PI Andrew Fountain and I were in McCarthy a couple of days ago, Andrew
got a message that one of the regional mountaineering schools wanted to
speak with him. They had lost a student climber in a moulin on the
Matanuska Glacier (see photo from 7/10 journal entry). A moulin is a
cavity which drains water into the interior of a glacier. While setting up
a camp with two others, the climbing student went off to fetch water. The
only trace of him was a half-filled pot of water at the mouth of the
moulin. We viewed a videotape of the scene where the accident had
occurred. A good sized stream flowed into the moulin, which had clearly
hampered any rescue efforts.
The mountaineering school was based in Palmer, so PI Andrew Fountain gave
them a call this morning and we drove over to talk with them. Originally,
we thought that they were interested in utilizing our borehole camera to
look for the body. But, as it turns out, a geotechnical company had
already lowered their camera about 500 feet into the moulin, and had not
observed the body. As an expert in glacier hydrology, the representatives
wanted to speak with PI Fountain about the structure and evolution of
moulins. They were frustrated that the lost climbing student had not been
located during previous efforts. Andrew explained that moulins typically
cascade into a glacier via a "plunge-pool" mechanism. They will flow
straight down for a relatively short distance, form a small pool, flow
horizontally for a distance, and then plunge vertically again. This
stair-step type mechanism can continue for quite some distance. What is
most puzzling is that moulins neck down - the diameter of the hole gets
smaller with depth. It was likely that the body was not down as far as the
original camera had extended. Perhaps the climber had maneuvered into a
side cavity to develop a survival strategy. Active glacier melting and
subsequent surface runoff into the moulin will cease later in the fall when
the glacier returns to its freezing mode. It is likely that another
recovery effort will be attempted at that time.
After this somber discussion at the climbing school, we proceeded to
Anchorage to unload equipment. First, we stopped at Dwight Bradley's farm
to drop off the hot water drill. The same welcoming committee was there
waiting for us - two horses, two llamas, and two chickens. We proceeded to
the Anchorage field office of the U.S. Geological Survey to return the
stream gauge. We then delivered the rest of the equipment to the shipping
company to be shipped to Portland State University. Tomorrow the glacier
crew will disband. PI Joe Walder, St. Olaf undergrad Andrew Malm, and PSU
grad students Michelle Cunico and Don Lindsay will head for home. PI
Andrew Fountain and I will be heading to Fairbanks. ARCUS (Arctic Research
Consortium of the United States), which is based in Fairbanks, is hosting
us for a tour of Arctic research facilities in the Fairbanks area.
