Mount K'lamm is a unique mountain of grand beauty. It rises singly and abruptly from a wide plain overgrown by young forest almost up to 1000 m above seal level and stretches approximately from west to east. Up to about half the mountain the steep slopes are covered with vigorous virgin forest, but the upper half is encompassed by mighty, almost vertical cliffs made of rock, over which water runs down in numerous gullies. Above the upper edge of the cliff there is high mountain vegetation compiled of bushes and small trees.
(from the original German〔 Hallier, H. 1896. Die botanische Erforschung Mittelborneos. ''Naturwissenschaftliche Wochenschrift'' 11(9): 75–79, 85–89, 97–101, 109–114.〕 in ''Pitcher Plants of the Old World'' )〔

After once again climbing a steep slope with ''Gleichenia'' thickets, one stands suddenly beneath the high enclosing rock wall of the mountain ring. The smooth water-washed stone seamed with water channels shows no variation in structure, and it appears almost as if the whole mountain was composed of a single monstrous block of rock. On this wall has been erected the steep 45 metre high rattan ladder; it is secured only at the bottom, in the middle and in the solid earth at the top, the rest lying free against the stone.
