Petes Post from Antarctica - September 2005
Heres the situation, said Lonnie, the Winter
SAR Leader. Jack and Jill were walking the Castle Rock Loop,
when they had an argument. Jack stormed off in anger, and has checked
back into McMurdo Station. Jill hasnt checked in, and is now
two hours overdue. Weve searched everywhere in town, and it
is assumed that she isnt here. Thats all the information
we have.
The temperature is minus 30 degC and theres a 20-knot northerly
wind. This means serious windchill - the human body will lose heat
at the same rate as on a calm day at minus 60 degC. Anyone stuck
in the open, or down a crevasse will be in serious trouble.
Pete, I want you to take command of the team today. Bo and
I are both unavailable.
My heart rate went up a notch or two. Why me? Id better do
a good job - someones life might depend on my decision-making.
The first step is to send out a hasty team to drive around the Castle
Rock Loop to check any shelters. They will concentrate on covering
the ground fast, rather than a thorough grid search. Meanwhile,
the rest of the team will assemble all our medical and rigging equipment
into another vehicle.
Jay, youre our primary medic. Can you take a small
medical kit and go with Rex and Jack. Id like you to take
a PistenBully vehicle and drive around the Castle Rock Loop from
the Arrival Heights end. Stop and check the NASA satellite dome,
the two emergency shelters, and anywhere you see open crevasses
or footsteps. Just take a climbing rope and your personal gear.
Lets get moving as quickly as possible, and give me a radio
check on MacOps frequency when you are mobile. Any questions or
suggestions?
First task accomplished. Id got the hasty team away.
Greg, can you please start loading the rest of the medical
gear into the Hagglunds. Deborah can help you. Well need the
Stokes Litter, KED and SKED, as well as the hypo-wrap and normal
medical kits. The rest of us will concentrate on loading all the
rigging gear and ropes. Well take the Arizona Vortex in case
we need to rescue Jill from a crevasse. Lets aim to be away
from here in fifteen minutes. Any questions or suggestions?
What else do we need; have I forgotten anything; have MacOps been
informed; is the doctor on standby? Is my personal gear all ready
to go; is my own radio on the right channel? Yes, it must be - theres
the test call from the hasty team.
Hedley, will you drive the Hagglunds. Greg, can you sit up
front and use the spotlight to look for footprints, especially when
we get near the icefall. Ill sit in the back seat so I can
concentrate on communications and logistics. Well drive out
to the other end of the Loop, and search the CosRay buildings as
we go. Well also search the emergency shelter at Silver City,
and the toilet building at the skifield. Id like to stop at
Crystals Crack where well walk along in front of the
Hagglunds for 200 yards with spotlights in case Jill walked off
the road and fell in the crevasse. Well do the same for the
big crevasse across the road up the Kiwi Ski Hill. Now does anyone
have any additional ideas, or is there anything Ive forgotten?
Once we were under way, my stress levels went down a bit. We searched
various buildings, and heard on the radio that the hasty team had
done the same. It was reasonably sheltered on our side of the hill,
but the hasty team reported very cold conditions with moderate visibility
on the windward side of the ridge. We checked the crevassed area
known as Crystals Crack, but there were no signs of any open
crevasses or any human trail. We continued up the hill beside the
skifield that Scott Base operates during the summer, and stopped
at a well-known crevasse marked with crossed flags.
Theres something in here, shouted Deborah, who
had quickly roped up and ventured to a collapsed part of the snow
bridge right beside the road. Its Jill, she said
once she shone the torch down the hole. Shes on a dodgy
snow bridge about ten metres down. I can see the crevasse is much
deeper than that maybe another fifty metres.
While I contacted the hasty team by radio, I asked Deb and Greg
to set up a personal snowstake anchor, and to abseil down to Jill.
Their first task would be to secure her from falling any further,
and provide reassurance and warmth while we prepared a hauling system
to extract her. They would put a cervical collar on Jill to support
her neck, and would manoeuvre her into the litter or KED that we
would be lowering down once we were ready. Hedleys job would
be to stay at the edge of the crevasse (roped to a personal anchor)
to provide a safety overview and a communications relay between
the people down the crevasse and the rest of us on the surface.
This is good, I thought to myself. Weve got three kiwis here
to boss around these ten yanks. We wont need any big discussions
about how to do things. Hedley will keep an eye on the people down
the slot and Blake can supervise the building of the belay system
and anchors. Ill supervise the construction of the main hauling
system, anchors, and assembling the Arizona Vortex. These Americans
are very good at what they do, but sometimes they waste too much
time talking about it first.
Building the anchors was quite quick. For each of the two rope
systems we dug four T-Slots and equalised them together into a bombproof
anchor. We were slightly cramped for space, because I decided to
keep everything on the area of snow that is surveyed and marked
as a road. This saved us having to probe out the surrounding areas
for hidden crevasses. We also used slings connected to hardpoints
on the Hagglunds vehicle as a backup anchor.
The hasty team had arrived mid way through the construction phase,
and all three of them quickly fitted into the new roles I allocated
them.
The Arizona Vortex is a large kitset tripod with a pulley that
we use at the edge of the crevasse or rock face we are raising the
victim from. It makes the top transition from vertical lifting much
easier, as the rope doesnt bite into the snow at the edge.
Because it is quite heavy, we often leave it behind. But it is perfect
when we can drive right up to the rescue area.
Within about 50 minutes, Jill and one of her attendants was hauled
out on a static rope with a 9:1 pulley system. Wed put her
in a KED to support her spine, since space in the crevasse was too
limited for a Stokes Litter to be practical. The belay team provided
a safety backup on a separate static rope using a tandem prussic
belay. The other rescuer had to prussic out of the slot on the same
rope she had used to abseil in on.
As soon as Jill was out, we put her on a backboard and placed her
in a hypo-wrap to warm her. We loaded her into the Hagglunds ready
for transportation to the medical centre. It only took a few minutes
to de-rig and clear the site, and we all headed back to McMurdo
for a debrief.
In all the years Ive been coming here, said Lonnie,
this has been the smoothest running scenario weve ever
had. Well done, everybody.
It was only a scenario, but the stress was real, the darkness was
real, and the cold was real. Personal safety was just as important
as in a real rescue too.
We havent had a real callout this season, and
I hope we dont have one. But weve got a very competent
team, and we take our training very seriously. And we have lots
of fun with our American friends.
