In addition to the 21 mountains of the Messner version, Stangl ascended further nine summits on three continents to also meet the requirements of the Bass version. This includes ascending the three highest peaks of Australian mainland Mount Ksciuszko, Mount Townsend and Mount Twynam. In course of the project, he anew climbed the three highest peaks of the Alps, Mont Blanc (4,810 m), Dufourspitze (4,634 m), and Dom (4,545 m), in 2013. According to one of multiple acknowledged scholary opinions, the border between Europe and Asia is to be located north of Caucasus, alongside the Kuma-Manych Depression. Considering that, the Alps would be the highest mountain range of Europe, making Mont Blanc, Dufourspitze and Dom the highest summits of the continent. Due to potential uncertainties regarding the measurement accuracy of altitudes, Stangl also climbed three additional mountains, Ngga Pulu (2007) und Puncak Trikora (2010) in Oceania, and Rwenzori (Margherita Peak) in Africa (2012).
