Wow, I've never seen Missouri soil do that. I'm sure it must have something to do with soil chemistry -- should have paid more attention in Soils class but they had so much boring Ag stuff that I kept dozing off.
i've always loved finding ice spikes like that in the backyard... we would often get them under a chunk of soil, sometimes you didnt see them right away, until you crunched on one nearby...
on a similar topic, i was trying to explain the concept of "frost heaves" to someone in texas the other day. They were completely baffled.
