Great arete climbing up a beautiful squarecut corner! Start standing and make a hard highstep move to gain the arete. Stick with it until you get a sloping jug at about two-thirds height. Gather your wits and courage, and figure out the best way to get to the top (hint: look way up high and to the left for a small positive handhold). Be careful up there...this one's a thriller!
The Walrus Boulder lies on top of a mound, downhill and a bit away from the central bouldering location at Devil's Den.
