Kigilyakh
Kigilyakh or kisiliyakh (Russian: кигиляхи; Yakut: киһилээх, romanized: kihilēx, lit. 'stone person', plural киһилээхлэрэ kihilēxlere) are pillar-like natural rock formations looking like tall monoliths standing more or less isolated. Usually they are composed of granite or sandstone shaped as a result of cryogenic weathering. Most kigilyakhs formed during the Early Cretaceous and are about 120 million years old.
