Superior - Keewenau Region Lake Ice
See more images and explanations here. |
Ice in cross section with bubble trains (~30 cm high). The air bubbles look like jellyfish tentacles.
The white top on this slab is probably snow ice, snow that at some point flooded and refroze to become
snow ice. |
Slush ice congregates in blobs, perhaps rotating in the current, leading to a generally rounded or oval shape.
The blobs jostle against one another in the waves, compacting and pushing up the ice around the edges,
forming the distinctive raised rims characteristic of pancakes. |
