In the western part of Qeshm Island and 70 km west of Qeshm city, near the village of ٍEast Chahu village, there is a gorge or valley in the heart of the highlands tat is calld Chahkooh Canyon. The walls of this valley have strange and amazing shapes. The niches and curves and twists that exist in the walls on both sides of this gorge fascinate every tourist.
The soil and rocks in this part of Qeshm Island, like most other parts of the island, are made of compacted sand. This sand structure, especially if combined with lime, is quite prone to erosion by natural factors such as water. The origin of this gorge and its strange and wonderful shapes are probably due to the influence of water and environmental factors on the land structure of this region.
In addition to the main gorge of Chahkooh, a narrower gorge or gap is located transversely in the middle of this canyon. Although the length of the straits is not very long, but they have given a unique beauty to this area of Qeshm Island.
From ancient times, some wells have been dug at the floor of the main gorge of Chah Kooh to store the water that flows in this valley when it rains. In areas such as Qeshm, which have been short of fresh water, any natural method has been used to conserve rainwater. The name of the mountain well is due to the existence of these wells that were dug in the bottom of the gorge. Chah kooh means the mountain of wells in persian.
