Wow! What a great, little, hidden gem. Just right of Hyperspace Roundup and left of Mail Ridge's 1st pitch is a great little 110' pitch connecting 3 cracks successively left of the last. 3 cruxes (somewhat strenuous) at 10b/c, 8+, 8+. Little alcove protected from some wind at the base. Goes up directly to a tree with slings and a ring. No star in either Rossiter guide, but it's a diamond in the rough.
This IS very nice. It should have a name. How about Special Delivery, keeping the mail theme?
I thought it was quite hard. I stopped halfway through the overhang with my hand on the bucket and tried to place a cam. I ended up lowering to the ground 4 times getting the gear in.
You can rap after the hard stuff from 2 bolts on the left, but the steep corner above is very nice. I was very tired by then, so it felt hard, but 8+ might be right as Leo says. Above that is easier for a while to a fun bulge. We angled left from there through the red band, past trees to finish on Lightning Crack.
