Due to the melting of the Northwall Firn from the SE peak of Ngga Pulu, this summit is now the highest point of the north ridge of Mount Carstensz. Furthermore, due to the complete vanishing of the Meren Glacier, its topographic prominence has increased from what would have been ~200 m to ~350 m. Sumantri could be considered the second highest independent mountain of Oceania, and it features on some Seven Second Summits lists.
