Mystery Mouse 2 is found just right of a corner system. MM1 is just to the left of the corner. Climb easy ground past a 14" roof (first bolt below it) to a larger roof above. Once you clip the third bolt, if you want the grade of the route to be anything close to 5.8, you have to climb up, more or less, the corner left of the bolt, then start traversing across to bolt #4. Pulling the roof move straight-on past bolt 3 is significantly harder than 5.8. Continue more vertical past bolt 5 to anchor.
Note: there is a plaque with the route name scratched in it at the base of the climb.
