Etc., St. George, Utah

It's pretty definitive. There is no good mountain biking where I live in Kanab. Great hiking trails are everywhere here though. There is the "telephone pole" route north of Fredonia near the "Clam Shell", it's not too bad. There are a couple of hours worth of biking available there. We usually have to go to the Hurricane/St. George area for good biking.
The "Bear Claw Poppy" in Bloomington is fun but not worth the two hour drive for us. The 12 mile loop is half pavement also; that is a drawback for me. In all fairness there are many options yet available in the same area. We need to explore them before I condemn.
The Cottonwood/Prospector/Church Rocks Loop (10 mile ride) is borderline acceptable for the driving needed. It is nearer to us and by the Coral Canyon golf course. It's a pretty good track but too much freeway vista and bumpy slickrock. The Prospector & Cottonwood sections are out-and-back.
So for us, nothing beats the Gooseberry Mesa area yet. It's pretty definitive.
We like the J.E.M. east and above Hurricane also. However, the "loop" (about 13 miles) ride comes back on a gravel road. I'm never a fan of that. S/T all the way would have to be an out-and-back ride on the John.Ellen.Mike. We got roped into the 20+ mile loop ride once. It's too much for us 60-year-olds.

Little Creek Mesa

UtahMountainBiking.com, good job on this one. We did the West Mesa/Magic Carpet Ride 9.5 mile loop. First two miles were easy and last two were easy. In between challenging with the terrain and route finding. Gooseberry, if marked like this one, would be much more difficult. This trail features great views on the rim and great slickrock (with plenty of accessory gymnastics available). We did the 9.5 in three hours including a good look at some mesa top ruins. I'll not tell you where they are in case you are a marauder. Oh you're not if you are out here. OK, at about 8.7 mi. (when you hit the double track) go right instead of left. Some good stuff on your left in about 1/2 mile at the top. DO NOT DISTURB THESE RUINS! So about a 10 1/2 mile ride then. It was kind of cool cairn seeking and riding, but very difficult for the middle section of this ride. Overall, 4 1/2 out of 5 stars. The first turn off of the paved highway is 1/2 mile west of the Gooseberry turnoff, south instead of north. Gooseberry is still the quintessential.

Addendum, Sep. 2, 2011
Went back to L. C. M. and rode Magic Carpet to North Point and back. It's marked "easiest" by utahmountainbiking.com. We didn't find it easier than the "easier" West Loop. Any way, that's not the point today. We met one of the trail builders (he and his bro' also did Gooseberry), Morgan. He showed us more old Indian stuff. It was neat stuff but I'm not telling. If you see "Trailbuilder" out here and he trusts you he may show you too. So it was like meeting the Pope without all of the gold. I'm trying to talk him into the "Grand Loop". 
Like it more coherent? Try "Epic Ride".
Oh yeah, one little beef with Utah Mountain Biking's description here: at mile 2.5 I'm sure that they mean "Fork L".
