@yurnidiot That's amazing! How does that happen? It would have to flash freeze to preserve the wave right?

@thestrangelet more pictures here, and some theory about it!

« Although the lake’s surface appears to have frozen waves, the prevailing theory is that these mounds and divots occur when snowdrifts form atop the lake, melt and refreeze. Over multiple melting and freezing cycles, the lake builds up with what appear to be wind-driven waves frozen in time »

@tsadiq @thestrangelet my understanding is when the lake freezes and covered in snow, as the wind blows off the snow, sections of uncovered ice sublimate faster so it develops a wave like pattern
