About 123 border markers of Indonesia-Malaysia in Kapuas Hulu region cannot be found. They may be buried by thick soil, carried by landslide, covered by bushed, or struck by tree. \"The expedition team has reached 67.3 kilometer from the total of 370 kilometer,\" the Commander Jayusman said on Saturday. They noted 530 boundary markers, in which 78 of them are damaged, from 4040 markers in Kapuas Hulu. The team also found some unnumbered markers lying on the ground. It may be a spare for the damaged markers. The team, Jayusman said, faced some challenges such as dense forest. There is also no land and water route for logistic dispatching. It should be delivered by helicopter. They also face bad communication signal as they cross blank spot area.
