In 2012, Kammerlander claimed to be the first man to have climbed the Seven Second Summits, the second highest summits on all seven continents. However, there are claims that Kammerlander may have only climbed the lower West Summit of Mount Logan. It is also claimed that Puncak Trikora, climbed by Kammerlander as part of the challenge, is not the second highest summit in Oceania. In which case Kammerlander will have to climb the main summit of Mount Logan, and climb Puncak Mandala in New Guinea to complete the Seven Second Summits.
