Update as of 1/9/10
Thanks to those that shared trail conditions beta last week, we spent 3.5 days in Hurricane/St. G and got a few good rides in. I just wanted to throw out a few observations based on our time down there.
All of the St. G valley trails (Prospector, Church Rocks, Barrels, Zen, Barrel Roll, Stucki, Green Valley, etc...) are about as good as they get right now. No snow, tacky dirt, and 50 degree temps. Glorious. Off the hook sweet.
The Hurricane-and-higher stuff is less ideal. Goulds/JEM/Virgin/Hurricane is rideable, although there is some grease in shady spots. I hesitate to say that it's fine to ride, as the greasy spots are soft enough that you'll leave ruts when you go there. Best bet is to ride these early and be done before ~11.
Guacamole is in great shape, but you'll NOT want to try to drive all the way to the top to park. Just before the road bangs that hard right and starts to climb steeply, PARK and ride the last ~1/4 mile. We didn't have this beta and almost slid off the road. BAD place to slide off the road. We backed down (doh!) and rode up, only to see that someone else had already slid their Subie 40' off the road and down the gnarly, steep embankment. Good luck getting that one out.
Slickrock Swamp/Rockville Bench is primo.
Goose is NOT YET READY. We had no problem driving in as far as the outhouse, but the road got FUGLY after that. And the trail wasn't much better. Very early on the snow/ice/goop was frozen but as the morning wore on things were thawing and it got soupy and sloppy fast. By ~10:30 any of the dirt/ST sections were a mess. We made it ~halfway out S. Rim and saw the writing on the wall, so we turned around and bailed to the road and got outta there. Hidden Canyon, North Rim, Windmills, Yellow, Grey Matter, and The New Trail SE of Windmill are all buried. If the temps stay high and no more precip falls, I'd say S. Rim will be ready by ~1/20. But the rest of the trails will need a lot longer. PLEASE learn from our mistake and give the Goose the time it needs to dry out. Ruts suck, almost as much as the people that leave them!
We didn't get to Little Creek but would expect it to be similar to or maybe a little worse than Goose because it has more in-the-trees-trail and more shade.
We didn't bother going to Grafton based on what we saw of it from Guac.
So there ya have it...
