The ridge top is a jagged knife edge, in some places only a few feet wide, with precipitous drops on either side. The highest point is 280 m asl. Lowland dipterocarp forest surrounds the ridge.(II) Climatic ConditionsThroughout the year, rainfall averages about 50 mm per week with heavier rains in November and December.
