Lena Pillars Nature Park.

Lena Pillars Nature Park, located along the Lena River in Russia's Sakha Republic (Yakutia), features dramatic 100-meter-high rock formations shaped by the region's extreme continental climate, with temperature ranges from -60°C in winter to +40°C in summer. These rock pillars are the result of frost shattering and freeze-thaw cycles, which create deep, steep gullies and isolate each pillar. Fluvial (river-related) processes also play a key role in shaping the formations.
