Horton, re reply 34:
Remind me why you think there is basalt at the top.
With respect to the beds seem defined by the density of the concretions I agree there is a relationship. However, as the concretions are clearly later than the bedding it is something in the bedding that is controlling the density of concretions, not the other way round.

What intrigues me is the fact that the beds seem defined by the density of blueberries. IE, the factors that controlled the blueberry formation controlled the bedding.
