|Cracks in the frozen glacial meltwater of Lake Fryxell|
Sometimes sinuous, sometimes rectilinear, these ribbon-like discontinuities form a graceful and intricate visual poetry on a frozen but ever-changing canvas.
We observe this intricate canvas of cracks as one might observe the last snapshot arriving from the past into the station of our sensory present.
A thundering pop summons us to sound.
The stresses causing ice cracks make somewhat expected snapping and popping sounds, but also make incongruous howling and screeching sounds.
The ice was here, the ice was there,When ice warms and expands, sounds emanate along the stressed surfaces. Similarly when ice cools and contracts, sounds emanate from the source of the disturbance.
The ice was all around;
It cracked and growled, and roared and howled,
Like noises in a swound!
