This is a fun easy traverse. It's always been part of my warm up circuit, or just a way to get some easy mileage. Could get pumpy for beginners on the left end....
You can start from the tree slab and traverse the tier below it from right to left, moving up jugs to avoid the crux on the Iron Cross. Keep going left to the next boulder and cruise up the south arete and then up the boulder above that and you will wind up back at the Beer Barrel.
