This next article, taken from Listverse, is about a band of man-made holes and the reason they were created. Makes for some interesting reading, I tell ya!
Band of Holes
A rather overlooked phenomenon in Pisco Valley lies right on the same plateau as the very well-known Nazca Lines. A band of shallow holes has been carved into rock covering miles of uneven surface.
These holes number into the thousands; each a meter wide and up to two meters deep. Considering that they had been carved into mountain rock, a lot of hard labor must have gone into creating them. There is no discernible pattern to the holes, with some being in a straight line and others just haphazardly dotting the rock surface.
The only certain thing about these mysterious carvings is that they were man-made. Their purpose and who created them remains an unsolved mystery. A recent theory has been put forward that the holes could be the remains of an ancient Inca tax system. Other theories include vertical burials, food/water collection points, and trail markings.
I know that i8f I had gone through all the trouble to dig those holes, I'd be damned sure I let folks know where they came from and that I made them, ya know? Gotta take credit for those kinds of things, I think.
Coffee out on the patio again this morning. Temps are going to be in the high 80s.
