This route is located at the leftmost part of the Three of a Kind Wall. This is a soft and pretty good quality sandstone face. Route goes straight up to the top, but beware of loose flakes.
Protection
A crashpad and someone to make sure you don't hit the tree if you fall.
Benningfield notes a "V6" to the right of "The Face" in Colorado Bouldering. Is he referring to the SDS to this problem or is there something in between "The Face" and "Round Pebble"?
There are 4 highball problems between The Face and The Culp Route (now known as Round Pebble). All are in the V4 to V6 range. Not sure what problem Benningfield may or may not be referencing. His guide to Flagstaff in Colorado Bouldering I covers a little more than a 1/3 of Flagstaff's boulder problems. I'll be putting the Three of Kind Wall Miniguide up on my blog soon. You'll be able to see it all there.
