I've done this trail a few times. The last time was about 20 YEARS AGO. The trail has gotten worse of course. I did this drive yesterday. I reduced the pictures to 1000 x 750 to conserve space. I hope they are OK.
This trail is on the road to Young, not too many miles after crossing the salt river headed north. It's a few miles north of the A-Cross road. You travel past the drainages area (on your left) then enter a canyon with an unmarked trail to your right. This is trail #489 in the following map.
This is what you'll see from the Salt River / Roosevelt Lake (the south side). The white dumps are from the abandoned Asbestos mine high up the mountain.
The trail climbs up the canyon and the north face of the mountain. I had to do my own spotting since asking my wife to look out her window was all the help I got. I'd walk a section then drive it. Taking this approach I ended up only taking picutres during the return trip, down the mountain.
So the first pic is where I decided to turn around. I found the limits of my FJ. That limit is the tires.
There had been one snow storm so far and I had hoped for a dry trail. Unfortunately the canyon was on the north face and didn't get any sun. About 2/3 up to the summit the ground was still saturated from the storm.
This is where I turned around. Ahead was a two stage climb through medium to large rocks with slick mud in between.
The following pic was taken at the climb just before the preceding pic. You can see the beginning of the snow here. There's a rock to the left of the leaning tree on the right in the picture. It's has a vertical face on it. In low range, A-Trac on, Dif locked, and slick mud on the tires I was only able to move sideways. Backing up slightly, using a bit of momentum I cleared it. There was an added obstacle that's kind of deceptive in the picture. Ahead and to the left is a flatened loose rock laying down. It's bigger than it looks. I'm sure it would hit at least the differential, it rocks side to side and it's close to 3ft across, probably several hundred pounds. So I had to make sure only my tire hit it.
The next climb was alot muddier and steeper so I called it quits.
This shows an easy section and one of the numerous trees that had been cut through to keep this trail open. I don't think any of this maintenance was official though.
Here's some images heading back down the trail to the Young Road.
My FJ is now officially pinstripped and I managed to slightly flatten this (what's it called? is it just protective? it doesn't look like it would provide much support):
This is a beautiful area with a spectacular view from the mine at the top. I was told that as of 3 years ago there were still cabins left from when the mine was in operation.
With a lift and proper tires, spotting might not be needed. (go for it!)
For those of us with no mud grips summer would be a better choice.
Interestingly the only other vehicle I saw was a Taco coming down. Go Toyota!
