Apart from either end, the border generally followed a ridge line throughout its length, rising to almost 2,500 metres in the Fifth Division. In the First Division, there were some roads, including a continuous road from Kuching to Brunei and around to Sandakan on the east coast of Sabah. There were no roads in the Fourth and Fifth Divisions or the Interior Residency, and in Third Division, there was only the coast road, which was some 150 miles from the border. Mapping was generally poor, as British maps of the country only showed tiny topographic detail. Indonesian maps were worse; veterans recall "a single black and white sheet for all of Kalimantan torn from a school textbook" in 1964.
