Last Rock-Geek Post of this Trip!

Our visit to Alibates Flint Quarry National Monument took us to a singular place on earth: the mountains where dolomite rock was turned into super-hard agate rock by silica ash particles from a volcanic eruption in Yellowstone 280 million years ago!! Nowhere else on earth has this occurred in a similar fashion, and it is eye-poppingly gorgeous. Have a look.

The public can only access these ancient quarries, which have been mined by indigenous peoples for at least 13,000 years, by getting in on a once-weekly 2-hour tour given by volunteers and rangers. There are over 700 quarry digs done by paleo Indians, antelope canyon Indians, Apache and Comanche Indians across the eras.  The site is VERY remote, and visitors CANNOT keep any of the fantastic rocks to be seen. But just knowing/seeing such beauty is a pretty cool thing, in and of itself. We’re happy campers.

On the way home to our MoHo, we saw many Swainson’s Hawks. They are as ubiquitous here as our Red-Tailed Hawks are at home. Big, burly and super-swoopy. Gorgeous raptors.
