This entry should be dated December 19th, 2018, just didn't write anything up because of laziness.
Long time no see, blog! So I was walking along a trail, when I thought I heard an abnormal sound and turned around. Strangely, there appeared to be ice in my tracks?! Had I finally discovered the power to create frozen stuff at will? Sadly, 'twas not the case - instead, the waterlogged ground had frozen and formed what I called "ice spires," but now realize is needle ice. That's linked to the Wikipedia article, the pictures and explanation are pretty much spot on there so I don't think I need to cover much, aside from a "lazy" overview.
Basically, the freezing air temperature "draws up" water from the soil to the surface, where it freezes, slowly building into a "mini tower" of ice.
I'll leave the rest of the "story" to be told in the video and pictures.
