Nat Geo has a feature on the French team working on the limstone karsts of the Sangkulirang Peninsula in Indonesian Borneo. Their finds from the last seven years are very promising, but development, mining and burning threatens all of that.
A Race to Save Ancient Human Secrets in Borneo
National Geographic, 11 November 2015
If you wanted to create a new UNESCO World Heritage Site, you might well look to the limestone landscape, or karst, on the Sangkulirang Peninsula in eastern Borneo. There, in the Indonesian province of East Kalimantan, you could cite the abundance of human and natural riches to justify your proposal.
For seven years, archaeologist Francois-Xavier Ricaut, from the University of Toulouse, and his French-Indonesian team, MAFBO (Mission Archéologique Franco-Indonésienne à Bornéo), have been excavating three sites in the Sangkulirang-Mangkalihat karst, which spans 3.7 million acres (1.5 million hectares).
In the karst, thick tropical forest shrouds weathered limestone spires, making it hard to get around, let alone do science. As a result, Ricaut says, “hardly any archaeological work has been done in this karst—we’re just beginning.”
After dogged sleuthing, Ricaut and his colleagues have found bones and charcoal that date back 35,000 years, the earliest such evidence of human occupation yet found in Kalimantan.
