This could prove interesting.

Researchers are investigating a cave in France, where neanderthals appear to have been breaking off stalagmites and using them for some purpose around 175,000 years ago:

I am interested to see what the dating techniques are that they use, but listening to one chap on the radio this morning, they are expecting to uncover evidence of neanderthal habitation in lower parts of the cave which have been covered by subsequent stalagmites, with their ongoing excavation work.

The fun job for the YEC'S on this one will be to attack stalagmite formation as a dating method. It is a fairly easily understood process, with a straightforward method of calculation. The calcite is deposited at a rate which is demonstrable through easy experimentation - and best of all, if you speed up water flow, to increase the volume of calcite available (in order to account for a much shorter timescale), you end up with a rate of water flow which washes away the calcite, before it has a chance to fall out of solution and contribute to stalagmite formation.

Fun and games ahead here.


Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
