Grinnell Point-- East Face
I have not climbed the route, and bad weather kept me from it during my last visit (on this day, I had a different climb planned), but you supposedly can climb the ridge in the foreground, get through the cliffs (Class 4), and find a goat trail traversing left to the south face, where a scrambling route leads to the summit ridge.
