Pass the Sputnik Boulder like you are going up to the Lower Satellites. When you get to the fork in the trail, instead of going left up the climbers trail next to the huge wall known as The Wave, go up the right fork of the trail to the base of The Second Flatiron.
Where the trail meets the base of the Second Flatiron, a cube-like boulder reminiscent of a Borg Cube on Star Trek is on your left. Go left just before the Borg Cube up a steep social trail parallelling the Second Flatiron, passing Nanoprobe V5 and the next boulder which is home to Gully Diver V5/6 sds. About 10 yards later, cut left onto a shelf that has a nice wall looming over it.
Trial By Fire begins left of the obvious and unclimbed dihedral from a sds on the strange flake, does some big moves out the 20 degree overhang to incut edges behind other flakes flakes and to ok edges at the lip. The topout is a cruxy challenge with not many choices for the hands. You will probably end up manteling one way or another to pull over the top. Somewhere between V5 and V6. A good afternoon circuit would be to try Nanoprobe, Gully Diver and Trial By Fire, which are all within 40 yards of one another, but still a short distance away from the main area.
A pad or two.
