This is the small pinnacle that you see up and to the right as you cross the bridge heading towards the Dome. Despite a 30 second approach and being in plain view, you will not be waiting in line for either of these two routes, although both are worth an attempt if you've climbed everything on the Dome.
L->R
A. Frogman?, 12, 1p, gear or TR. B. Chimney, 6, 1p, gear.
Getting There
Park in the same pulloff as for the Dome and the Elephant Buttresses. Cross the main bridge and the pinnacle will almost be directly in front of you, being slightly to the right and above the water pipe. To avoid erosion, please do not scramble up the steep, loose hillside directly beneath the pinnacle. An easier approach is to follow the trail as if heading for the dome. There will be a side trail leading back towards the pinnacle, placing you on the right side of the pinnacle.
The Classics

I lost a BD ATC-Guide two weeks ago or so up in Boulder Canyon. I think I lost it around the Dome/Elephant Butresses area (but could be somewhere else). I'm just a poor college kid with no money and now no belay device. If you found it and returned it, I would be extremely grateful and would be more than happy to reward you with some beer.
