The images are photographs of ice cracks.
I found them on several freshwater ponds over the last few days. The ponds had been frozen, partially thawed and then re-frozen, a process which seemed to result in the formations which you’re looking at. I shot them in early morning light or late in the day –hence the warmer tone.
For me, they evoke astrophotography and pictographs.
