As temperatures dropped sharply in China's northernmost city, Mohe, Heilongjiang province, residents and tourists were pleasantly surprised by some spectacular winter scenery.

Located in the Guanyin Mountain Scenic Area, Lianhua Lake has frozen and presents unusal ice bubbles. The crystal bubbles in various shapes spread into an area of more than 3,000 square meters on the lake, attracting sightseers and photographers.

The bubbles can only appear in extremely cold areas when methane released by plants on the bottom of the lake is encased in water, which freezes as it rises.
