Repeat enough times and you have bibble stacks. The size of the bubbles would depend on the frequency of gas bubbles and how fast the ice is forming.

The bubbles are coming from a source at specific locations. Say, decomposing plant matter on the bottom.
decomposing vegetation is one option, I agree, another might be carbonated springs which would be my guess,
the stacking - not sure if it a freezing action as much as possible floating up because of weight and being caught in different temperature levels??
I have no expertise to offer, just exercising my W A G privileges
in any case, great photos recording the events [/COLOR="Silver"]
