Looks to be correct the website says to use springhill trailhead instead.

Oh great even tho that one is closer I've never been to that trail head. Probably rode all over the top of it and didn't even know oooooor never even got close to it is most likely the case.
I do know that they have a sheriff in a 900 un-governed rzr that will run down anything in the place so really have to be on your p's and q's. Be sure to have all the state stickers etc.
