Some clarifications, as I see them:
“Groundwater” does NOT equal “underground river”.
There is, indeed, usable water at some depth or other under nearly every bit of ground out there. Locally, one can drill, in some cases, as shallowly as 20 feet and hit drinkable water (though they usually go down past that to help assure cleanliness.)
Most groundwater, however, either does not “flow” or flows relatively slowly.
For example, here in town (a small city overlooking Cook Inlet) waterwells can be drilled as shallowly as 30 feet to get potable water, yet the bluff overlooking the beach is between 50 and 60 feet high.
Water does indeed ooze out of the exposed bluff wall, but it doesn’t “flow”- it could hardly be called a trickle, lt alone a “river”.
Rapidly-flowing underground water tends to create sinkholes, since the water tends to carry away soil. A ‘river’ also assumes there’s some place for the water to go to- an undergound cavern which eventually empties into an aboveground river or lake, for example. (Obviously that assumes changes in elevation between the two.)
Basically, groundwater is nearly everywhere, while underground rivers are pretty rare and subject to unique geological formations.
I can’t speak for the Lower 48, but up here, with very few exeptions, one could blindfold a stoned monkey, spin him around a dozen times, and drill wherever he happened to throw up, and you’d hit potable water between 30 and 90 feet down. Guaranteed.
Any half-assed jerk with a pointy stick could pass themselves off as a dowser and have nearly a 100% sucess rate- this, obviously, however does NOT mean that dowsing is an authentic skill, or that said dowser-jerk found the Fabled Underground River. I strongly suspect that the majority of the States would provide similar results.
Pete- you’re picking apart a bit where Randi stated essentially what I just explained, as a mild, offfhand remark, and extrapolating that into a huge web of lies and deceit somehow.
Just to humour me a bit, perhaps you could catalogue a few of these additional “lies” or fraudulent claims, other than his supposed disbelief in “underground rivers”.
