Dan (age 51) was born in Portland, Oregon,
spent several years growing up in Calcutta, India, and now lives in Hunt
Valley, Maryland with his wife Kathy and three kids. Dan is an
Anesthesiologist practicing in Frederick, Md. He loves the outdoors and as a
teenager spent a lot of time hiking the Appalachian trail, whitewater
rafting in Western Maryland and spelunking in the tri-state area.
Several years ago he and long time friend David Pohl summited Mt. Rainier in
During the last 10 years Dan has completed the Baltimore and New York
marathons and participated in a number of charity events including the 2009
and 2010 Multiple Sclerosis 150 mile bike rides.
Looking for another challenge, Dan wanted to combine his next climb with
fundraising efforts for Child Health Foundation. At almost 23,000 feet,
Argentina's Aconcagua seemed to be the perfect combination of height,
weather and terrain for the next big challenge.
Dan Sack reached the 23,000 ft. peak of Mt. Aconcagua (Argentina) on January
20th, 2011 and has returned safely. He raised over $9,000 for Child Health Foundation.
Perhaps you’d like to add to that and celebrate this accomplishment.
Below are the pictures and the story of his climb in his words.

After a long flight, I arrived in Mendoza and was greeted by the Mountain Guides. The next few days were filled with preparation and on day 4, other
members of the group and I entered the park and headed off for a 3-mile hike to out first camp, Confluencia (11,010 ft). After setting up camp, we were
off on our first acclimatization hike. Four hours later, we arrived at Plaza Francia lookout point (13,400 ft), and were able to get our first glimpse of
this awesome mountain with impressive views of the south face.
After several days of acclimatizing, and another day to rest, it was now day 14, and we were ready for our next push to higher camp. We reached Berlin
Camp (19,600 ft.) after about 4 to 5 hours and set up camp knowing that we might have to spend an extra day here due to strong winds. The forecast was
predicting strong winds over the next day and half reaching over 100 mph at the summit. Obviously a summit attempt in those conditions would be futile.
The forecast turned out to be accurate as we learned that on the first night trying to keep our tents from collapsing under 60 to 70 mph gusts. The next
morning we discovered several tents around us had been flattened and the climbers had to squeeze in with their colleagues. The winds subsided and on
Day 16 we began our push for the summit.
With an early morning wake up call (around 3am), we began preparing for our climb in darkness and frigid cold temperatures. Under the dim lights of our
headlamps we pushed on to Independencia shelter at 21,476. Later, we pushed on across the “big traverse” and up the “canaleta” groove. After climbing
that particularly steep and strenuous section we traversed “Guanaco’s” ridge which took us to the highest point in the western hemisphere, the summit of
Aconcagua at 22,841 ft.
We celebrated and stayed for 45 min. to an hour, took pictures and measured our oxygen levels (58%) before heading back down;
about a 15 hr. day round trip.
A great and memorable adventure. (never to be repeated). At least not on this mountain. :-)
About Child Health Foundation
Child Health Foundation was established in 1985 as a non-profit, public charity [501(c)3] to prevent and treat life-threatening communicable
diseases of infants and children in the United States and abroad.
Our mission is "to save the greatest number of children's lives at the lowest possible cost." We accomplish this through our unique network of
health professionals and organizations committed to improving health policies and practices. We operate as an independent agent of change,
seeking and promoting more effective, easily-delivered and less-expensive methods to prevent illness and death of children, such as
oral rehydration therapy to prevent dehydration, immunizations, and breastfeeding.
How high is Aconcagua?
Aconcagua's name has roots in the Quechua language and when translated means "The Sentinel of Stone." At 22,841 feet (6,962m) Aconcagua in
Argentina is the highest peak in the world outside of the Himalayas.
The mountain stands on the border of Chile and Argentina and has a very steep and massive face on its south side and a gentle slope on the
north, with a huge glacier - the Polish glacier - flowing to the east and a series of aretes and couloirs to the west. It is one of the
world's "Seven Summits".

How long will the climb take?
Known as the highest trek in the world, it will take 19 days and require 14,000 feet of elevation gain to reach the summit. The climb is broken
down into two phases. The first phase is a 3-day trek from 8,600 feet (2,620m) to Plaza de Mulas base camp at 14,300 ft (4358m) . The second
phase is the trek to the high camps and the summit at 22,841 ft (6961m).

How cold will it be?
Mountains are known for unpredictable weather and Aconcagua is no exception. It is known for its blasting winds and cold temperatures.
Days of clear sunny skies are normal on Aconcagua, but the mountain does receive storms during the summer months due to its proximity to the
Pacific Ocean, and the moist, humid winds blowing west from there. As this air rises over the slopes of the Andes, its speed increases and it
condenses to form lenticular clouds on the summit, also known as viento blanco, or white wind. Given the potential for challenging weather
conditions getting to the summit is not guaranteed, even for well-prepared climbers.

What are the effects of altitude?
One of the biggest issues at high altitude is acclimatization. Above 10,000 feet (3,048m) there is a noticeable decrease in air pressure. It feels like
you are breathing through a straw, making even the easiest tasks a challenge. Everything must be done in slow motion. Travel to extreme
altitudes can sometimes lead to medical problems, from the mild symptoms of acute mountain sickness to more serious conditions such as high altitude
pulmonary edema (HAPE) and high altitude cerebral edema (HACE). The higher the altitude, the higher the risk. While supplemental oxygen and other
medical remedies can help significantly, moving to a lower altitude is sometimes necessary to alleviate symptoms.
