I camped at the Onion Creek Campground, less than a mile south from highway 128 about half way to Cisco from Moab.
In the morning I wanted a ride, but a truly mellow ride. The Onion Creek road goes up to Fisher Valley, and it looked to be graded gravel all the way up. No complicated route-finding. No anaerobic short climbs. Sounded like a deal. And I'd never explored the Castle Valley area, so it seemed like a good fit.
I'll just let this series of panorama shots tell the story. Other than one thing: this is a good ride to take somebody else's bike on. You cross Onion Creek 22 times, only once on a bridge. I've heard that it's called Onion Creek because it's so laced with salts and arsenic that it tastes more or less like an onion. Up near the entry to the Fisher Valley, it smells like sulfur, not so much below.
But all those shallow crossings and then the sandy exits spraying wet sand onto the drivetrain make a sloppy mess of grinding paste. My bike was a fugly mess when I finished.
Now, on to the photos:
I came to just the verge of the Fisher Valley. It's the flat platform visible in the middle left.
