It's a traverse with several possibilities (best to worst, IMHO): Left to Right: start matched on big, bumpy ledge near left end of north face (as per Shaved Chakra), traverse with feet just above ground level, finish at right end high point (as per Will). Right to Left: Start 3/4 to right end with good right angling incut edge and ok lower left hand (as per Will), go up then left with feet near the ground, finish just before left arete (as per Shaved Chakra). Variations (any combo of these options): R to L: start far right on boulder and/or finish at left arete. Problem 13a on beta photo L to R: start on left arete and/or finish far right on north face where boulder is shorter. Problem 13b R to L long version: continue around the left arete onto the east face. V5, Land of the Lost, if you stay below the lips and use the smaller face holds and finish as per Holly (see beta photo). Problem 13c

See Gimme Boulder North Face beta photo, problem #13 and variations.
