At 8,848 m/29,028 ft Mount Everest is the world's highest peak. Even the trek to Base Camp is arduous. Climbers aiming for the summit must survive the extreme conditions of the 'Death Zone' and perform great feats of endurance. I am planning to use the North Col Route. Technically, it is more challenging than the South side but it does not have the ice fall danger. Another appealing aspect of the Everest North Ridge route is that it offers a view of Everest virtually the whole route from base camp. In May 2011, I have climbed up to 8,600 m/ 28,380 ft on the North side of Mount Everest, 250m/825ft short of the summit. In April 2012 I broke two ribs in Tibet on the way to the mountain and had to turn back.In April 2014 I got viral infestion at 7,000 m / 22,965 ft. and in May 2015, I experienced an earthquake of 7.8 Richter scale at 6400 m / 21,000 ft. At that time, my quest for climbing Everest changed to helping my Sherpa and other families in the Himalayas.

Aconcagua, which translates as "Stone Sentinel" is 6,962m/22,840 ft, making it the highest mountain in the Americas and the highest mountain outside of Asia. This spectacular mountain is surrounded by numerous peaks over 20,000 ft. and the surrounding lowlands (up to 13,000 ft.) consist of beautiful desert landscapes with a large diversity of flora and fauna. I have experienced Aconcagua’s strong winds and the extreme cold at high altitude several times, but finally was able to enjoy the summit view.

Mt. McKinley, or Denali, meaning the "Great One," in the native Athabascan language, was my number three of my Seven Summits. Mt. McKinley rises steeply from its base at just over 2,000 feet above sea level to over 20,000 feet, a gain in elevation which is greater than Mt. Everest. Good weather is definitely a key success factor during the long climb to the summit of Denali. We were lucky and made it to the top as one of the last expeditions in July 2009. What an experience, and all the heavy loads were forgotten.

Mount Kilimanjaro rises majestically from a rolling plain close to the Indian Ocean from hot savanna to a barren and frigid 3-1/2 mile high peak. It's the highest mountain in Africa and one of the largest free standing mountains in the world. Climbing Kilimanjaro is a must-do challenge for almost every trekker and mountaineer in the world. Uhuru Peak, how the top of the volcano is called, was my first of the Seven Summits. It is really an unique experience to hike through such a rich vegetation (banana trees, rain forest, high steppe, high desert) and end up in the snow of Kilimanjaro.

Mt. Elbrus is the highest point of Europe. The Caucasus Main Range is considered to be a border between Europe to the North and Asia to the South. Two main Mt. Elbrus summits are about 11 km (6.8 miles) to the North from the Main Range, inside European territory. Western summit 5633 m and Eastern summit 5621 m with the Saddle elevation 5416 m. It was a great experience to visit this remote area near Chechnya and climb the “Top of Europe”. Looking across the Caucasus Range into Georgia was quite amazing.

Vinson Massif, at 78°35'S, 85°25'W is 21km (13 miles) long and 13km (8 miles) wide. It lies on the southern part of the main ridge of the Sentinel Range. Named for Carl G Vinson, a Georgia congressman and a major force in 20th century US Antarctic exploration, it was first climbed in December 1966 by a combined group from the American Alpine Club and the National Science Foundation. It has been an extraordinary trip to one of the most remote, windiest and coldest places on earth. I am so grateful that I was able to do this. This was an experience which I will remember for the rest of my life.

Mount Kosciuszko is the highest mountain on the flattest and smallest continent. A thoroughly uninspiring peak, Kosciuszko gets a lot of abuse, particularly from those who claim that the Australia/Oceania continent's rightful contribution to the "Seven Summits". The challenge on this mountain was definitely not technical nature or altitude, but orientation since I got caught in a white out during my descent.
