The Kasara Gorge is located in the valley of the Ardon River, on the northern slope of the Greater Caucasus Range, and its depth reaches up to 1,000 meters.
The Military Ossetian Road runs along the Kassar Gorge.
The gorge owes its name to the plant of the Gypsophila family, more precisely – its Ossetian name kassar, which grows abundantly here. Vakhushti Bagrationi (1696 – 1757), a Georgian historian and geographer, noted that the Kassar Gorge is very rich in minerals: “Here there is an abundance of lead ore, sulfur of excellent quality, and also silver ore.”
