Bukit Kelam
Gunung Kelam is a huge granite dome near Sintang in central West Kalimantan province famous for its pitcher plants. It was first written about by German botanist Johannes Gottfried Hallier in 1894. Everyone has heard of the mighty Ayers Rock in Australia. But if Gunung Kelam can be considered one huge rock, then West Kalimantan is home to what just might be the largest rock on the planet.
