MRE starts with a hard pull into the crack followed by shallow stemming and pulling on pockets. The crack steepens and narrows down at the top then pulls over to the chains.
This climb is on the east side of Mars Rock, the dome seen on the east (left) as you approach Moon Rock from the highway. The route is on the far right side of the wall starting in a right facing crack just a couple feet from The Exterminator.
A single set of cams with an extra or two in the smaller sizes if you want to sew it up. Shares chain anchors with The Exterminator.
