The Nostrils

Start standing with hands matched on the "nostrils" of the lion and mantel directly over the middle of the nose.  No cheating by going out left or right.  Just a pure mantel over the overhanging middle section.  Burly.

In an old Supertopo discussion from 2007, John Bachar himself described this boulder has having some "bad ass mantels," including this one.

Mantel over the most overhanging part of the "nose" on the Lion's Head boulder.
