Cave Enlargement Pills - No RX-Required to Order

Just the other day Elizabeth and I were watching a documentary about early man, something on the order of a million years old. The archeologists were excavating a cave in Spain and finding neolithic skeletons at the bottom of a pit. The part that caught both of our attention was that the pit was at the bottom of the cave, a 45 minute crawl. It was the kind of location that neolithic man would not have managed to reach let alone gone and died in. The documentary ended by suggesting that the pit was originally open to the ground and the neolithic men were dumping bodies into the pit as a form of early burial. 

The implication is that so much deposition occurred in the intervening years that a hillside was placed and a cave opened up to allow underground access to the pit. All this in a million years. 

Sure, as a geologist, I like to think I have a pretty good sense of time and scale. After all, a 200 foot deposit only needs 0.0024 inches/year over a million years. This is a dust film. The hard part is imagining a deposit that could remain stable and also form a cave. Caves are typically limestone, which only forms under water, usually deep water. That does not make a whole lot of sense in this case. 

This paper is interesting because it suggests that cave formation is more dynamic than many geologists would expect. The waters that carve away at underground openings can also slowly fill in those cracks and deposit material. The point I took from the paper is that the chemistry of the water is crucial. If the water is not saturated in carbonate, limestone will more easily be dissolved. 

Does the paper explain how neolithic man was able to bury their comrades? No, the geology of that excavation seems very interesting and I suspect that the documentary makers made a mistake or the scientists were taking liberties about their interpretation.

Most conceptual models of epigenic conduit development assume that conduits sourcing karst springs form as water that is undersaturated with respect to carbonate minerals flows from recharge to discharge points. This process is not possible in springs fed by
