Located in Bone District, Bone Bolango Regency, at 0°22’13.02” N and 123°27’49.83” E, this geosite features granodiorite, a type of plutonic igneous rock that formed deep beneath the Earth's surface during the Early to Middle Miocene, about 23.3–11.6 million years ago. The rock has a grayish-white color, a massive structure with sheet joints, and a coarse-grained texture, allowing visitors to easily see its main minerals: quartz, plagioclase, and biotite. These large, well-formed mineral crystals are the result of slow cooling beneath the Earth's surface over millions of years.
The surrounding landscape consists of gently rolling structural hills, shaped by the region's geological history. One of the most remarkable features of the site is its steep waterfall, which was formed and controlled by geological structures within the bedrock. Together, the ancient granodiorite, rolling hills, and spectacular waterfall tell the story of the powerful geological processes that have shaped this landscape over millions of years, making the site an exciting destination for visitors interested in nature, geology, and the Earth's history.
