In the warm up area of the Ahwahnee's there are a number of fun problems. You can start on heinous slopers to start the easy dihedral that you can see to the right (that's called Iceberg). Or you can tackle the bulge which is called Liceberg (for Left Iceberg and a pun on the classic traverse in Font called l'iceberg). It's silly but fun.
Finding the problem is easy. It's just to the right of Funky Chicken in the Ahwahnee's.
