Barito River
The Bakumpai people once had a kingdom that is much older than the kingdoms of the Banjar region, but because of supernatural abilities the kingdom had to be relocated to the Barito River and its king is known with the name "Datuk Barito". From Marabahan, they spread to the streams of Barito River. According to local folklore, there is an area in Murung Raya Regency called Muara Untu where in the beginning it was a jungle controlled by a race of jinn named "Untu". Later there was a Bakumpai man named, Raghuy who traveled and lived there. Until today if observed from the lineage of the Muara Untu people, they would trace their ancestors to Raghuy.
