It's on the road that goes from Lehi over towards Tooele.  I forget the name/ number of the road, though.  Basically, go down 15, take the main Lehi exit, go west through Lehi, and about 20 miles or so later, once the road starts heading back towards the north, you'll see a pull off to the right with a big dirt parking lot.  That's the trailhead.  I've PM'd you my # if you guys want to meet up at the gas station in Lehi I mentioned in the first post.  As far as difficulty, there's everything there... dirt track to class five that you'll need a winch to get up.
