Geologically there are several limestone features along the foothills of the mountains, some of them containing beautiful caves. Long ago,  these caves were coral reefs which have been uplifted from the sea at a rate of few millimeters per year. The uplifting occurs by process of colliding ocean floors and drifting continents.

The infinitely slow collision and the enormous forces involved have led to the formation of a high mountain and volcanic zones. Only 1800 years ago, during glacial times, the peaks of the park Mt. Leuser, Mt. Kemiri and other, were still covered by glaciers snow and ice. The sea level at that time was more than 80 m lower than today and the islands of Sumatra, Java, and Borneo formed one huge land mass which connected via Malaysia to the Asian Mainland.
