Ice Forms

While exploring the ice cavern, I oberved these icicles which appeared as stalagtites and stalagmites. Interesting forms emerge when water freezes and melts repeatedly.
My quinzhee sure is reluctant to melt completely. It will probably be the last thing to melt in the yard. I'll be sure to make one every year. Maybe next year I'll get a chance to actually sleep in it before it melts.
