Don't ride in the spring when the creek is high as you have to cross it at the end of the trail. Look for a road going north from the Amasa Back road just north of the powerline. Follow road down to the intersection with Rockstacker
- this is the beginning of Jackson's.
This is not for the faint of heart but is not as crazy as some people make it out to be. The exposed parts of the trail are not very technical but its a long ways down to the river. You probably won't even notice the exposure because your so focused on the trail and how much fun your having. Over all, it's not as hard as Portal
. There is one spot in particular towards the bottom that is the crux. It rides better than it looks but scope it before hand. You get to the bottom and hit Kane Creek. Turn right and follow a traverse that hopefully keeps you above the creek. Near the parking you turn left and cross the creek.
