BETA PHOTO: Royal Arch, Hammerhead, Third Flatiron. Via Google...
This rock is also know as Yodeling Moves due to the route found on the rock. The east ridge is 400 feet long and ends to north of the large summit block that extends to the south. This summit block is overhanging on all sides, but does alow passage by the "Yodeling Moves
" route (5.0) on its west face. The route also contains Boulder's longest arch, which you climb over on the ridge line. A Flatiron classic!
Follow the Royal Arch trail to the top of the switch backs. As you head down the trail, you will pass a trail head on the left and a base of a Flatiron on the right (~150 feet). 25 feet beyond this point, a faint trail heads to the west for 50 feet to the base of the climb. The "hammerhead" summit should be obvious.

: ... : Hammerhead
This classic 4th Class scramble starts at the base of Hammerhead and goes up towards the obvious arch. This arch is apparently the longest arch in the Flatirons and has some great exposure once on the arch.Once on the arch continue up the line towards the notch on your left. Once at this notch climb down a bit and off the rock. At this point you have several options, one is call it quits, another is ascend the north face via a short 5.7 pitch,, and the other and probably best option is to go ...[more] Browse More Classics in CO

I tried to find the start of east ridge today, but I couldn't seem to find it. My understanding is you take the Royal Arch trail past Sentinel Path and start to move west once you get towards Woods Quarry trail. My problem was I never figured out where Woods Quarry trail was and didn't see the unmarked post that is supposed to be around there. Any suggestions?

From the sign at the top of Sentinel Pass, walk about 300 steps (+/-) down the trail. You should be by a rectangular block of rock on a level section of the trail. About 50 feet above the trail is the feature in question, you're there! As of July 2011, there is a fairly fresh anchor on top of the summit block, although downclimbing the buckets is recommended.

No reason not to solo this. But if you're too chicken, like me to down-climb Yodeling Moves, the anchor has a fat new piece of cord to rap from as of 10-31-12....

The Woods Quarry trail junction is unmarked and easily missed. When you are coming down steeply from Sentinel Pass, the junction is where the trail stops going down and begins traversing south. I don't recall the "rectangular block of rock" mentioned by Mic, but only 100-200 feet past this junction is where the faint trail heads up to the Hammerhead.
It you leave the trail at Sentinel Pass and head west up an indistinct ridge, you will encounter the summit of the Hammerhead in maybe 500 feet. This is the descent route.
