Team prepares for Carstensz Pyramid expedition!!

The Madison Mountaineering team is preparing for a expedition to the highest island peak in the world! This massive rock formation is the largest mountain in Indonesia as well as the Australian continent. Carstensz Pyramid, or Puncak Jaya, is one of the least climbed peaks in the “7 Summits” and a formidable objective located in Papua, Indonesia. Our expedition will begin in the beautiful island of Bali, where the team will then fly to Timika then Sugapa to begin the trek to base camp. Madison Mountaineering’s high end logistics, local staff relationships, and mountain guide experience ensure the group will be well taken care of throughout this expedition.


Carstensz Pyramid was developed by the collision between the Australian and Pacific tectonic plates. The rock formation that exists today is composed of limestone that rises from the thick forest below to just over 16,000′. This mountain ascent will be a exciting adventure filled with many challenging rock formations. Along the ascent the team will push through multiple glacier fields across the mountain such as Carstensz Glacier. Upon reaching the peak the summit will typically be free of ice. The team’s rock climbing ability to ascents includes mostly 5th class terrain on fixed ropes. Stay tuned as this expedition prepares to launch!!
