Question:
How are you all doing? Is everything on schedule? I would
like to try to climb Everest but I only have one arm which
was an incident in my army career dec 1989! Could a disabled
person do it?
Good luck!

Response from Pete Athans:
A one-armed climber was making the attempt this year, but
has returned unsuccessful. Tom Whittaker, a single amputee
(lower leg) will attempt Everest next year. Yes, it is
possible.
Question:
To the members of the Everest Expedition: We have been
following the 1997 Everest Expedition with great interest
and admiration for your courage and skills in undertaking
this great adventure. One of the things we noticed in the
photo by David Breashears on the Home Page, was the absence
of any belay ropes. Has anyone ever slipped off the ladder
while crossing the crevasse? It looks like this would be a
pretty tricky and dangerous maneuver while carrying a heavy
pack and wearing crampons! We both wish you the best of luck
and hope the high winds subside pretty soon so you can make
the summit attempt.

Response from Pete Athans:
You are correct in observing the problems crossing ladders.
Actually there are two protective ropes on either side that
a climber attaches his or her harness to.
Question:
Do your lungs have a burning sensation all the time because
of the air pressure? How far can you climb without a major
rest? Is the wind constant? Or does it come in bursts? How
do you keep the tents in the ice without blowing away? Good
luck and we are all watching your climb.
George Wild
Montvale, NJ
Response from Pete Athans:
We do not experience any burning sensation. We usually rest
about 10 minutes per each hour of activity. Wind is
variable. The tents are attached to ice with ice screws or
snow pickets.
Comment:
I've been diligently following your online reports, and find
myself unexpectedly anxious and expectant as the team
departs on its summit push. I'm writing simply to express my
best wishes to David, Pete, Ed, Guy, Veikka, Jangbu, Tashi,
and the rest of you bound for the top (and to send my
regards to Howard at BC as well). You are all in my
thoughts. Climb hard, be safe, and keep up the good work.
Sincerely yours,
Jon Krakauer
Seattle, WA
Response from Ed Viesturs:
Jon: Thanks for your note. All is well, we're ready to go
but it's very windy up high, so we're patiently waiting for
a break in the weather. We had hoped for a May 7 summit, but
the wind gods did not allow us to make our attempt. So, the
waiting game begins. Hope your book is a great success.
Let's have a beer when I get back to Seattle. Ed.
Question:
Here is a difficult question: In Jon Krakauer's book, "Into
Thin Air," he tells of the massive efforts made by many
expeditions to keep Everest clean by removing spent oxygen
bottles and so forth. Yet in the book he recounts his
sighting of two frozen corpses on the mountain as his team
approached Camp II in 1996, one of which had been there for
over a decade according to his guide. Why are bodies left on
the mountain? That seems odd.
Danny Evans
Irvine, CA
Response from David Breashears:
Bodies are much heavier and much more difficult to remove
than garbage. For instance, a Sherpa can easily carry 4-6
empty oxygen bottles down from the South Col. But it would
require 6-8 Sherpas to carry down one body. To further
complicate the issue, the Sherpas, who always provide the
man-power for the removal of bodies, are extremely
superstitious and wary of dead bodies and often refuse to go
near them, even if the deceased are familiar to them. We
feel that it would be improper to demand that the Sherpas
move the bodies of the deceased when they are often so
opposed to it. Also, although it is rare, the relatives of
the deceased sometimes request that the bodies be left on
the mountain. But, it is the difficult logistics and
enormous effort required to bring a body down that often
precludes us from removing bodies from Everest. It is
important to note that bringing bodies down Everest is also
a time consuming and dangerous activity and one has to ask
if it is worth risking lives to bring down someone who is
dead.
Question:
To David Carter, I was wondering if any climbers have ever
tried taking a blood transfusion before their summit
attempt, to see if that would help deliver more oxygen to
the brain during the climb? Good luck,
Dave Roberts
Greenfield, IN
P.S. Maybe we could climb Red River Gorge sometime.
Response from Dr. Howard Donner:
At altitude, it is not simply a matter of oxygen carrying
capacity (the amount of red blood cells), but rather how
efficiently oxygen can be delivered to the necessary tissues
including the brain, heart, lungs and muscles. With
increasing red blood cells ("hematocrit"), blood viscosity
can increase to the point where profusion (or delivery) is
impaired. On ascent to altitude hematocrit goes up almost
immediately due to mild dehydration, i.e. an increasing the
concentration of red cells. Within weeks new red blood cells
are produced at altitude at a rate that the body can use
efficiently. In 1983, climbing scientists on Everest
attempted to remove red blood cells, and found no change in
their performance.
Question:
What effect does high altitude have on metabolism? Is the
extreme cold also a factor? What changes in weight can be
expected as a result, especially at Camp IV and above?
W.L.
Kansas
Response from Dr. Howard Donner
Metabolism is a very broad term. Initially on ascent, there
is an increase in adrenaline-like compounds which increase
metabolic rate and result in increases in blood pressure and
heart rate. The body also attempts to become more efficient
by increasing mitochondrial density and increasing oxidative
enzymes (enzymes involved in metabolism). Mitochondria are
the power factories for human cells. Interestingly, actual
metabolic depression of membrane Na+/K+ ATPase, in the
brain, is not seen at levels of hypoxia typically
encountered in climbers. This means that the brain remains
normal from an energetics (metabolic) standpoint. If by
metabolism you mean performance, VO2
Max (maximal oxygen uptake) has been shown to decrease
steadily with increases in altitude. The extreme cold
requires greater caloric intake to maintain normal body
temperature, and at altitude climbers feel they have more
trouble staying warm. The amount of weight loss seen in
climbers at Mt. Everest is variable. Our climbers often lose
little weight. Historically, Everest climbers have lost up
to 40 lbs or more on a single expedition. Climbers arriving
with less excess body fat tend to lose less body fat.
Comment:
Hello Dave Carter and team. My name is Jason. My dad and I
have been following your trek and want to wish you luck for
the summit, and for your safe return. I hope you can reply
back. But if you can't, then I just hope you reach the
top!!! Thanks.
Jason Donahue
Uniontown, PA
Response from David Carter:
Thanks for your interest. It's great that you two are able
to follow us on the Web site. Keep logging on as we attempt
our summit climb.
Question:
To: David Carter
Hello from Methodist Sports Medicine Center in Indianapolis!
We were wondering how your reconstructed ankles were holding
up during your climb. We also know that you have had some
knee tendonitis that we have treated you for over the last
couple of years and were curious as to how, if at all, it
was affecting you. Are you wearing any ankle or knee braces
for support? Best of luck from the staff of M.S.M.C. and
everyone at Peak Performance Fitness Center.
Indianapolis, IN
Response from David Carter:
My ankles are holding up well. I've had no problem
whatsoever. Concerning the knee tendonitis—nothing.
Basically the only problem I've had in my legs is I have an
infected big toe. Other than that I feel fine, and hopefully
we won't be doing any further business together! Thanks for
your support.
