The Meat Wall is the north-facing wall of the Green Monster Slab. The wall is mostly fairly steep and split by several crack systems.
Unusually for Rock Canyon there are primarily trad routes on this wall. The Ruckman guide shows 6 named routes; there are two bolted Darren Knezek routes at the left side of the wall that are not in the guidebook.
From the parking lot head east on the road/trail. Just after the chlorine treatment building and just before the alcove known as The Kitchen turn right (south) and head uphill. On your left you will see the Bolt Slab, a smooth, west-facing formation (if you see a big crack you've gone too far and are looking at the Green Monster Slab).
Either scramble up the north-facing ledges to the right of the Bolt Slab (scarier), or scramble past the north face around to the top of Bolt Slab and then down to reach the base of Meat Wall (slightly longer).
