November 20, 2008: Whole Lotta Hole

It's clearly water doing it, but I don't understand why the water eroded straight down instead of making a more horizontal cavern with stalactites and stalagmites. Those caverns are in limestone too.

It's so perfectly straight in the photos and we all know that water almost never goes perfectly straight. It winds and meanders all over the place following the path of least resistance.

Barefoot's karst topography link makes a lot of sense the way it's drawn, but I'm not fully convinced. This shaft reminds me of peeing into a snow bank. Dogs, I mean, not me. You would never catch me peeing into a snowbank.

Not just any water... falling water. Water does go in a perfectly straight line when gravity makes it fall straight down and there is no wind.

Makes me think of Gandalf and the Balrog...
