IMG guide Dan Zokaites called in on the sat phone to report that they had reached the summit of Sumantri, one of the other main peaks in the Carstensz area. Sumantri (4870 m;15,978 ft) is north of Carstensz Pyramid on the other side of the valley, and it is home to one of the only (and fast receding) glaciers in south Asia. Dan reports they did some rock scrambling, then used crampons on the glaciated portion, then climbed class 4 rock to the summit. Good job you guys, I bet there have not been many people to summit this peak!
