The fifth expedition to Sultan Kudarat, the Philippines, was another fun and productive trip to the island nation. More than 8 kilometers of new cave passages were mapped including several large rooms and passages. Most of the survey was in well-decorated river caves. The team has completed many maps of caves of the area, is working on a book project for the caves of the region, and looks forward to a sixth expedition in the future to return to the many leads. The expeditions take place in close cooperation with Philippine cavers and government organizations.
