Forgive my ignorance are the raft bits on a water surface or just free hanging halfway down the tite?

yeah thats what I assumed, u would think the water must of been at that level for some time to form them, then dropped suddenly.
pretty cool though.

Here's a gour pool in Ingleborough Cave which we've watched for some time. Soon after its inlet flowstone stops flowing in dry weather the water level in the pool slowly starts to fall. (There is evidently slow leakage between the crystals from which the calcite is composed.) After about 2 weeks of dry weather it sometimes dries up completely. This picture shows it after 5 dry days.
If a stalactite grows down into such a pool which has dried up, then conditions change and it refills with water with a lot of dissolved limestone in it, a flange can grow out from the stalactite at water level. Later, if the water disappears again, the result may look like Badlad's recently discovered formations. Those in his photo are a particularly fine example! Maybe evidence of climate change?
