We traveled past Navaho sandstone formations adorned with the bright yellow autumn leaves of single leaf ash.
Where the Green River carved a path 1000 feet below us, Coco and I looked down in awe. "Huh?" Coco was thinking. "I've jumped a few gullies, but do they really think I can jump this? Give me a break!"
Across the deep canyon, the peninsula of land is a point of the Spur, where we have ridden in previous years. The silted area on the inside of the oxbow is called Cottonwood Bottoms. You can see that some of the cottonwood trees, far, far below, have begun their autumn change. To the left of the oxboy, you can see Horsethief Trail, once used by outlaws, but now mostly a Jeep trail.
We encountered several unexpected pools of water, all very close to the overlook. These are called tanks, or potholes, or ephemeral pools. I like the latter name. It sounds more impressive. The horses didn't care what they were called, but they did enjoy a good long drink in each one.
This one had tall grass. Boss almost slipped off the sandstone into the pool as he stretched his neck to bite off every possible stem. He even stuck his nose underwater to get at more grass. It must've been pretty sweet stuff.
Another pool was especially deep, with vegetation around it.
The amazing thing about these pools was that they teemed with life.
Fairy shrimp have a long fossil record, evolving over the last 500 million years. They are left over from the time when inland seas covered the Great Basin.

"The longtail tadpole shrimp is considered a living fossil because its basic prehistoric morphology has changed little in the last 70 million years, exactly matching their ancient fossils. Triops longicaudatus is one of the oldest animal species still in existence." - Wikipedia
With all of our desert riding, we had never seen any of these shrimp species before. There's always something new to be found if you look closely enough.
On the way back to camp, we stopped to let the boys munch some Indian rice grass. Coco seemed to want a little bit of loving.
