A historic series of achievements has unfolded on Carstensz Pyramid (4,884 m) – Oceania’s highest peak – with major milestones by climbers from Nepal, Mongolia, and El Salvador, all reported by 14 Peaks Expedition.

First, veteran Nepali mountaineer Lakpa Sherpa, widely known as Makalu Lakpa, set an exceptional record by summiting Carstensz Pyramid four times in just nine days.
According to the expedition team, Lakpa reached the top on October 19, 22, 24, and 27, each time guiding international climbers to the summit. His fourth ascent on October 27 is being called an extraordinary milestone for any Nepali mountain guide. The team credited his “dedication and technical expertise” for the safe success of all summit attempts.

At the same time, two international climbers marked personal and national firsts.

According to 14 Peaks Expedition, Ariunzul Chuluunbaatar of Mongolia also summited Carstensz Pyramid at 6:00 a.m. local time on October 27. With this climb, she has now completed her Seven Summits and finished the Explorers Grand Slam. Ariunzul is a watercolor artist and businesswoman, and she had already summited Mount Everest with 14 Peaks Expedition in the spring season.

In another historic moment, Alfa Karina Valle Arrue from El Salvador became the first Salvadoran to summit Carstensz Pyramid. After this ascent, she still has two peaks left – Mount Elbrus in Europe and Mount Vinson in Antarctica – to complete her own Seven Summits quest.

14 Peaks also highlighted the crucial role of Arlen, the local guide, whose support was described as invaluable for the safety and success of the expedition.

Carstensz Pyramid, also known as Puncak Jaya, is located in Indonesia’s Papua province. It is known for its technical rock climbing, exposed terrain, and logistical difficulty. Multiple summits in such a short time – and at this level of commitment – are rare.

This week’s successes bring together three powerful stories: a Nepali guide setting a high-altitude guiding record, a Mongolian climber completing one of the hardest adventure objectives in the world, and a Salvadoran climber making national history.
