crystalline pipe organs

In a manner similar to the movement of water through my basement, melting snow gravitates underground and moves through cracks in the rocks. It is common along the cuts in roadsides to see where this water has exited these fissures, and freezes once it hits the cold air. This is a pedestrian explanation for the makings of some beautiful ice formations. These have always reminded me of crystalline pipe organs. This photo is from the fall actually, but you get the idea.
