This rock would make a great first solo experience. Start at the low point of the rock, climb up and right until you reach the center of the face, and the then head straight up on great easy rock for some 150 feet.

Descent - follow the Mallory Cave "scramble gully" back down to the trail.


Standard rack.


The Shark's Fin and Mallory Flatironette are totally different formations: one below and one above the cave.

Mallory Flatironette is below the cave, is 3rd/4th Class (IMO), starts down near the Mallory Cave Trail, and ends about 50 feet below the cave entrance.

Shark's Fin is the steep, narrow spire above the cave, which goes at 5.2-5.7. Oct 1, 2017

^^^ The Shark's Fin is the formation above the cave and between The Hand and The Finger. The Mallory Flatironette is the small slab down and left of the terminus of the cave trail. Its singular summit lies just down and left (S/SE) of the cave entrance.

Some confusion here is probably caused by the height in the description, which is may be accurate, but only places you perhaps 60 or 70' above the point on the Mallory Cave Trail where it leaves dirt and goes onto rock. Sep 6, 2014

I have known this formation as "The Shark Fin" although the "Mallory Flatironette" makes sense with its proximity above the famous cave. Jul 22, 2010
