My 7 year old and I were driving our golf cart on a cool little trail we call "Laughing Skull trail" near Blythe Calif.
Laughlin Skull because it reminded my 7 year old of the trail in the Disney Pecos Bill Cartoon where the Cowboys are hot and drunk and the desert skulls all start laughing at them.
We were heading to a little desert bar and grill my 7 year old calls the DIAAHREE-OH.
It's real name is the Del Rio, but some friends got sick on the food, hence the new name from the kids.
The trail goes through an area call JackAss flats, and the Jackass flats Country club.
The Jackass Flats country club, is a 9 hole desert golf course carved in the desert by retired "snowbird" campers during their stays at this area during the winter.
A fun free simple golf course in the absolute middle of nowhere.
Then, we came upon a small BLM Kiosk with historical info about the general area, and we stopped and read it.
It mentioned over 1000 years ago, the residents of the area carved Intaglios mostly seen from the air, some still visible today.
We seached around and found a few, then checked with google maps when we got back to the RV and this is what we found.
The ancient Colorado River residents carved huge pictures in the desert floor called Intaglios still visible today:
This human figure has a dog with it.
Estimated to be 1000 years old.
