Underground river found beneath the Amazon

I have some research plots in the Cimarron National Grassland on the banks of the Cimarron River, about five miles above the point where it permanently emerges from the ground. Above that, most of its flow is underground. The channel is so vague that my cruising team installed a line of plots right across it and up the south side without realizing they'd crossed. Water in the upper stretches is such a rare event that when water does manage to flow all the way across the Grassland, it's considered a newsworthy event and the local paper carries pictures and an article!

Perhaps some "new" animals could be discovered...

Perhaps we will find more evidence of the hollow earth? Or maybe it will remain classified eh?...

This is so freaking awesome. Too bad ABC is too hard to believe on ANYTHING.

hmm not too hard to imagine. the hassayampa river that runs past wickenburg arizona flows underground just south of the town. and does not rise to the surface after that point.
