This route seems to form up less frequently than Silk Road. It follows the gully that ends in the gash.
It was originally posted under the name, "Third Flatiron East Face Center".
Start at the bench where the regular summer route begins. From here make your way into the gully on your left (we ended up climbing down around 60 ft before some less slabby terrain allowed an easy transition into the gully). Follow the gully to the top. The crux will likely be between the tree and the spot where the gully doglegs slightly to the left, however the climbing is interesting almost the entire way. If one is feeling adventurous, one can summit, however tunneling through the gash to the bench where the second of the rappels from the summit is provides some entertainment, too.
Protection
Rock rack from small nuts to fist size should allow all available cracks to be used for gear.
