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.
How about calling it "Going Postal"...obviously they lost their marbles labeling it 5.10b/c. Ivan, I got licked on this one too! Stamp it 5.10+ then send it....
Do this route as an alternate to the first pitch of Handcracker Direct for a great 5.10 link-up. After passing the first 5.8 section, just go right to the belay. Some guy named Sergio said he did the first linkup of these pitches and called it "asscracker direct".
