Three Indonesian students from Airlangga University in Surabaya, East Java, have made it to the top of Denali in Alaska.

Denali, the original native name of Mount McKinley, is the highest mountain peak in North America.

The students, Muhammad Faishal Tamimi, Mochamad Roby Yahya and Yasak, reportedly reached the 6,164-meter-high Denali summit on Thursday morning.

The trio departed from Indonesia on May 16 and spent 21 days climbing the mountain.

To reach the peak, the students had to face several obstacles, such as snowstorms, narrow slopes and extreme cold weather, while carrying 50-kilogram packs of supplies comprising food, oxygen and special equipment.

Prior to the trip, all three had to go through intensive training, which included running for one-and-a-half hours at a time and climbing several mountains in East Java.

Airlangga Indonesia Denali Expedition (Aidex) manager Wahyu Nur Wahid told tempo.co that the Airlangga University’s mountaineering club had been planning to climb Denali since 1994.

The expedition, which reportedly cost Rp 800 million (US$60,160), was supported by the university, property management company PT PP Properti and state-owned pawn shop PT Pegadaian. (jes/kes)
