Engil'chek Glacier, Alpine glacier in Tian Shan Mountains, Kyrgyzstan.
Engil'chek Glacier is one of the longest valley glaciers outside the polar regions, located in the Tian Shan mountain range in Kyrgyzstan. It has two main branches, the North and South Engil'chek, which merge and flow together through a wide high-mountain valley.
The glacier was first mapped and studied by Russian explorers in the late 19th century. Soviet expeditions later established a permanent base camp in the 20th century, which still serves as the main starting point for mountain expeditions in the area today.
The glacier sits at the foot of two of Central Asia's highest peaks, Khan Tengri and Pik Pobeda, which draw mountaineers from around the world each summer. The base camp at the edge of the ice has become a gathering point where climbers of many nationalities meet before heading higher.
Access to the glacier requires a border zone permit, which must be arranged in advance before entering the area. Reaching the base camp typically involves either a multi-day trek or a helicopter flight from the nearest town, so planning ahead is important.
A lake called Merzbacher Lake forms each year at the edge of the North Engil'chek branch, fills with meltwater, and then drains completely in just a few days. The water flows out beneath the ice and reappears further down the valley, a cycle that draws scientists from around the world.
