Tahquitz Canyon.

This canyon is on the Cahuilla reservation in Palm Springs, CA.  It was home to an ancient Cahuilla village, and is now open to the public.   There is more historical information at www.tahquitzcanyon.com.  Some of these photos were shown on Larry Harrop's blog two years ago. Here is the entrance to the canyon.

The Cahuilla claim to be descendents of Fox Indians who migrated to the area over a thousand years ago.  This is a sacred rock where the village was sited.

The area in front of this boulder is paved with rocks.  Donations?
The boulder to the right  in the  photo below is called the Fox Dress boulder, after a legend about a maiden who turned herself into a boulder. It looks like an erratic on bedrock.

 This does resemble the boulder in Manitou (p. 218), but I think the location is a different canyon on the reservation.  Maybe next time...
Further along the trail, some striking boulders.

A small shelter, with a flat rock inside.  Was this some sort of work surface?

Maybe it was a metate, a grinding stone.  The oval stone to the right may have been  the mano (hand-held grinder). I've seen other metates in rock shelters.  Maybe the Indian women preferred to grind the corn out of the  sun and wind.
Looking back towards Palm Springs.

Finally, the waterfall at the top of the canyon.

And just below the waterfall on the other side of the canyon, a bird head effigy with donations underneath.

Further down the trail is some sort of platform or niche.

At the site of the Cahuilla village, some  propped rocks cross a large boulder.  They remind me of ants.

The photo didn't come out because of glare, but high in the cliffs were some crevices sealed with carefully stacked rocks.  These might have been granaries, or food caches in case of raids.
This local resident also thinks the noonday sun is too strong!
