In Sahollan village, 42 km south-east of Mahabad city is located between Mahabad-Bukan and 28 km from Bukan city in West Azarbaijan province. The height of the cave reaches the surface of the lake to 50 meters and the depth of water reaches 30 meters in some places. The difference in temperature inside and outside the cave is between 10 and 15 degrees.
Sahollan means “frost” in Kurdish, and locals call the cave “Kune Kutter”, the nest of the pigeon. The reason for this is the existence of a large number of pigeon nests inside the cave. This cave is on the list of national natural monuments of Iran.
The date of the discovery of the cave is unknown. Because they were housed in villages and residential areas, and people have always used it as a haven and place for hunting. But officially, Jacques Demorgan, along with the villagers of Soholan, began to build a small wooden boat and the way to see the water and draw a map of the cave that corresponds 60% to the current reality, this time coinciding with the death of Bokan ruler Saifuddin Khan Macri.
