Lake Michigan 2 days ago
Frozen sand and strong winds, it kind of looks like Bryce Canyon "Hoodoos".

Very unusual looking formations there. Did the sand that was there blow up on dunes or hills close by? Could those formations be critter borrows that filled with wet sand then froze? If not, it is hard me as an outsider to figure out the process.

Re: Lake Michigan 2 days ago
Sand is always moving, borne by wind and water.
The prevailing wind carries particles of dry sand from the Prairies to the East.
The Sun warms land faster than water, so during the day breezes come off the water toward the land, depositing sand on the beaches.
Dry sand is always drifting, moved by the wind. This can create Dunes, a bit inland that are stabilized by moisture, grasses and other vegetation.
In developed beach areas, the dry sand is free to drift, covering roads, yards and structures. It has to be resisted with 'snow-fencing' or removed with road-graders and front-loaders, to put it back on the beach.
In the photo I posted, the beach sand was wet and frozen. Swirling wind currents have slowly dried some of the sand and carried grains away, sculpting the columns of still wet & frozen sand.
The grains that were carried off may be building up a Dune, covering someone's cottage porch, or out in the Lake and in the process of being washed ashore.
