Dirt Brothers: Charles Swenson --- Alibates Flint Quarry

Alibates Flint Quarries National Park!
Dirt Brother Charles Swenson takes us there!

This is a boulder which has been worked, showing the red bands of Alibates flint a little clearer. The method which was cited by the guide and several other sources is that fires were built on the boulder itself, and after heating it as much as possible water was then thrown on the heated stone,
causing it to shatter and giving it a distinctive fragmented appearance. It was then much knocked into smaller fragments with the hammerstones, with smaller portions possibly worked loose with some sort of prying tools. Deer antlers have been found at some surrounding quarry sites, leading to speculation that they were used for this purpose.
