It rises singly and abruptly from a wide plain overgrown by young forest almost up to 1000 m above sea level and stretches approximately from west to east.

Hallier described it as follows: 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.

[translated from the original Dutch[5] and German[4][6] in Pitcher Plants of Borneo][1]Leptospermum trees form a sparse canopy on the mountain's upper slopes, while grasses and Sphagnum moss cover the ground.
