Layer by Layer

Short answer: On frozen lakes, ice thickens in layers as cold spells come and go; temperature swings, wind and pressure crack and stack the sheets into ridges and shards. The Reel's captions describe ice sheets formed from layers of ice in cold temperatures, varying with the intensity of temperature fluctuations.

The footage, credited to all.litvinova, shows layered, broken ice on a frozen lake.
