Hike past WI4 Moonlight for close to another kilometer until the creek bends leftwards. You'll pass a campsite area then see some mixed climbs. Follow the path along the left rock wall (high and away from the creek) using wire lines and fixed rope to make your way back down towards the creek. Keep hiking in and you'll see WI3- B2, WI4 Slurpee, then further down WI4+ Green Monster. Green Monster is quite a ways in from the traverse section. Roughly 1.5 hours of hiking back to the parking lot.
