Swans also feed in the lowland lakes. Cranes are common in both low and highlands. Nunapik is found in the interior terrain. This is where rivers become fresh water, and salt water is not usually present. Another important feature of nunapik is sod, which the Cup ik people use for making sod houses.
Sod also has many other uses.
For instance, it can be used for building emergency shelters on the tundra. Also, traditional smokehouses are made of sod and driftwood. Mountains Besides the highland and the lowland areas, the other landforms in the region are mountains, which are generally less than 2,000 feet high. Anything bigger then 2,000 would be a massive mountain for us. The Askinuk Mountains are to the north of Chevak.
