Shirley following P10 of Moon Goddess Arete (numbering per Supertopo). This is a long (~160 foot) class 4 traverse pitch that skirts the base of Ibrium Tower. Do not follow this pitch all the way to a “minor arete”. Instead belay roughly where the last piece of pro is (kink in rope) and head up a wide “gully” from there for P11 (September 5, 2004).
