The Fist or Hippo Head (depending on whose guidebook you use) sits high above the Southern end of the East side of Green Mountain and is the highest Flatiron on its East face.
Technically it is part of the same rock strata as Angel's Way which is the Third Ridge on the North side of Skunk Canyon, although it is indeed separate from that ridge. Due to its location, it is typically climbed after completing any of the Northern Skunk Canyon Ridges or the Fifth Flatiron.
The climbs on the Fist are great and the views are hard to beat.
Probably the best hiking approach is to start from Chataqua and follow the Royal Arch trail to the Arch and then hike West staying south of the Fifth Flatiron and North of the Hourglass. The trail is clear but steep and loose at times. The trail will deposit you on the East face of the Fist. From here, you'll need to navigate around it depending on the route you choose.
From the Fist, you can hike Northeast to the Greeman trail for a nicer descent back to Chataqua or descend East as described above.
This route is just right (as seen from below) of the rappel. Its first 25 feet ascend a broken, nearly overhanging section below a crack. After that, you move into a fist wide crack that quickly expands into offwidth. The crux comes some 40 feet off the ground and involves climbing and mostly exiting some 10 feet of offwidth onto the ledge just below the summit blocks.Descent - rappel North from slings.

The rappel down the West face is off of an old #10 hex & big tricam with an old, faded sling with 2 rings, an old, faded sling, and a bit of rope. The pieces really don't fit the crack ideally, but they are adequate. Pull down and not up. You rappel down a crack on the West Face, which may be the "North Face" 5.7 crack, but it may not be.
