Mountains of Indonesia

Presenting Indonesia's Ultras over 2500m!

I decided to narrow the list of Indonesian mountains to just the main prominent peaks, and felt that taking into account their prominence (or 'independence' if you will) was the best way to do so. Since ultra-prominent peaks, or 'Ultras', are considered peaks that have a topographic prominence of 1500m or more, I decided to remove any peak lower than that, and maintained the elevation cut-off at 2500m for an O2 sat of <75% at the summit. This reduced the final list of mountains to a total of 46 peaks, and omitted some significant peaks such as Bukit Raya, which is the highest peak in Kalimantan and one of Indonesia's 'Seven Summits'.

* Prominence is defined as the "height of a mountain's summit by the vertical distance between it and the lowest contour line encircling it but containing no higher summit within it", and has been described as an "objective measurement that is strongly correlated with the subjective significance of a summit". Since peaks with high prominence are either the highest point on a massif or an isolated peak, they also tend to have the best views!

Peak Locations

The positions of the mountains in the table below have been verified with Geoname, and the prominence has been determined using algorithms on Google Fusion Tables that were developed by Andrew Kirmse [The data can now be accessed here since Google Fusion Tables was discontinued in the end of 2019].
