Needle Ice

The ground froze last night ...
This morning, when the sun came out, I found these interesting ice heave formations. It amazes me that such a delicate piece of frozen water can lift up rocks like this!

I did some research, and learned that this type of ice is called "needle ice", frost heave, or frost beard. The National Snow & Ice Data Center (NSIDC) describes needle ice as follows: "Needle ice can form any place where the ground freezes. It crunches when stepped on. Needle ice is made up of thin ice crystals. The ice crystals grow upward, starting a few centimeters (inches) underground. If the air stays cold enough, needle ice can grow forty centimeters (16") long."

What the NSIDC doesn't say, however, is that if a deer runs through the ice patch, it leaves behind a heart!!!
