The hill is a volcanic rock-shelter site and a part of volcano mouth of 2 kilometres (1.2 mi) in diameter.

[1][2] It is surrounded by numerous isolated hills and mountains with most representing the sites of extinct volcanoes ranging from Pliocene to Quaternary in age.

[3] The site has been identified as the largest pottery making factory in Southeast Asia during the Neolithic period.

[1] An ethno-archaeological study shows that such pottery making is still practised by the Bajau community in Semporna to this day.

The hill provides evidence of prehistoric sea trade and one of the world's longest human movement dating back 3,000 years.
