. Continue ( 5

. Turn left and continue west toward a broad saddle above the northwest end of the basin - 7
. Near 13,100', and before reaching the bump on the ridge shown in 9
, angle right ( 10

Now near 13,300', turn right and follow the ridge northeast toward the summit - 14
. Stay near the ridge crest and ascend sometimes-loose talus ( 16
