Not a scientist but I coulkd guess that the spikes could actually be formed by originally being ingeous intrusions, and being a stronger stone than the stone around the formations. This way, water could erode away the softer stone (over a VERY long time) leaving the pinnacles standing alone, and then the water is gone after time. That of course is assuming that the pinnacles are stone. I do like the mystery aspect of it.
