Unusual Ice

On a steep clay slope at Potato Creek State Park (North Liberty, Indiana), I found these unusual ice formations right on the surface of the ground. My guess is that moisture was seeping out of the clay and freezing.

Saw these ice formations near a canal path in Nevada City, CA last week while walking. Forgot my camera that day, so I can't prove it.

Cool, aren't they?

Yes, they are cool indeed. Cold, in fact! I'm glad someone besides me got to see such an interesting natural phenomenon! Thanks for commenting Intrepid!

I think this is called "needle ice" and yes, the pores in the compact clayey soil are slowly pushing the ice out... like a spaghetti maker.

Thanks Kathleen. Good to know!
