Was on a hike today and was very observant of the huge rocks and the ground that create it.
The rocks were being 'scored' (a notch or line cut or scratched into a surface), like it was clay, and would break off according to the score over an unknown period of time.
Did a google search and sure enough...

I wouldn't be surprised if a sound/resonance technique was used to dissipate the water.According to the caller, the mysteries had actually been solved by Joseph Davidovits, Director of the Geopolymer Institute in St. Quentin, France, more than two decades ago. Davidovits claimed that the stones of the pyramids were actually made of a very early form of concrete created using a mixture of limestone, clay, lime, and water.
"It was at this point in the conversation that I burst out laughing," Barsoum said. If the pyramids were indeed cast, he said, someone should have proven it beyond a doubt by now, in this day and age, with just a few hours of electron microscopy.
It turned out that nobody had completely proven the theory … yet.
"What started as a two-hour project turned into a five-year odyssey that I undertook with one of my graduate students, Adrish Ganguly, and a colleague in France, Gilles Hug," Barsoum said.
A year and a half later, after extensive scanning electron microscope observations and other testing, Barsoum and his research group finally began to draw some conclusions about the pyramids. They found that the tiniest structures within the inner and outer casing stones were indeed consistent with a reconstituted limestone. The cement binding the limestone aggregate was either silicon dioxide (the building block of quartz) or a calcium and magnesium-rich silicate mineral.
I am certain that one or two generations of native americans can cover a mountain with megalithic rocks.
