Highland Caves of Kalimantan

It was not until two weeks after their arrival in the Indonesian portion of Borneo that this team obtained their permit to proceed to the previously unexplored Muller Range of Eastern Kalimantan. Heavy rain, leeches, food poisoning and suspected malaria then compounded their difficulties, but despite this the expedition was a success. 8.5km of new passage were explored, surveyed and photographed, and a valuable reconnaissance car­ried out in three other caves. Once the problems are forgotten, it seems likely that a return trip will be made.
