Kolyma has reserves of limestone.
The indigenous peoples of this region include the Evens, Koryaks, Yupiks, Chukchis, Orochs, Chuvans and Itelmens, who traditionally lived from fishing along the Sea of Okhotsk coast or from reindeer herding in the River Kolyma valley
 Limestone is readily available and relatively easy to cut into blocks or more elaborate carving
