New wall as of 9/25/15. The climb on the left, "420 Club", starts directly below the overhang at the end of the trail. For "John" and "Dive Bar" climb past the two bolts on the right to the shelf. Gets sun in the early afternoon.

Getting There 

Wall is just left of the The Dollar Store. Use trail to Dollar Store and go straight instead of going right.

Mike, it's good to see you're still out there doing it, let's climb at the Ems together soon. There is still room at the Emeralds for development. When the snow melts a bit more we have a couple of walls to bolt on the Benches. You up for drilling and cleaning??

Off to the left of the listed climbs, there's a 2-bolt anchor. Apparently this is a toprope or project without lead bolts installed yet, so don't waste your time squinting at the wall looking for a bolt line (like I did)!
