@wild.calm4: A frozen lake at sunset, singing. As the temperature changes, the ice expands, shifts and cracks, and those vibrations race through the sheet as zaps, whale-like calls and deep hums. High notes travel through the ice faster than low ones, so each crack arrives as a falling "pew." Real recording. Sound on. 🧊 #WildCalm #SingingIce #FrozenLake #NatureSounds #WinterSounds
