Thin Slice is one of the best 5.10a trad climbs at the City. It is found on the north east side of Parking Lot rock, just east of Cario (5.11a).

The climb starts in a right facing dihedral, and follows a juggy crack with good gear. A small bulge is pulled and the crux finger crack is just above. Figure out the tricky moves along a finger crack and you will arrive at a ledge with 2 bolts. An extra finger sized cam (#1 friend) will be helpful in the upper finger crack.


Gear to 2 inches, extra finger sized cams

Another great line. Don't miss this one. I felt a tad harder than Bloody Fingers, and a lot less secure. I remember thinking to myself as I looked up at it, "This doesn't look all that great". Man, was I wrong.

I actually thought this one was kinda easy for the grade. Easier than Bloody Fingers and WAAAAY easier than Double Cracks. Outstanding, intimidating climb.

So good! It climbs like a sport climb until the finger jams in the upper crack...

Looking up from the base I opt out of leading this route as it looks, well, "thin". I'm not a huge fan of using only small gear. What a mistake! The route is for ladies fingers and a great size. sm-med nuts, TCU's to 2" cams. Watch for chopped ropes in the cracks. Chain anchors.

I won't make the same mistake next time.

I also thought it was harder than Bloody Fingers and not as good.

This felt more sustained to me than Bloody Fingers, but still great fun. The bottom part does climb like a sport climb. The whole route took great gear. A 60M rope doesn't quite reach down to the nice ledge for the TR.

A fantastic line that shouldn’t be missed. I felt it was on par with other 10a’s in the area in terms of difficulty. Aesthetically speaking the route is inspiring.

Holy crap this thing is fun. Gear-protected overhanging jugs to a splitter finger crack. Great feet the whole way. Very photogenic with great gear the whole way -- do it!

Absolutely great climbing, wow!! I felt it was a little soft for the grade in the area.

I would definitely recommend you rappel this route. You can see the remnants of more than one cut rope jammed in the crack at the top. Hook your rope over a large bump on the way down and rap just right of the crack. You can still clean all of your gear. I also needed a much smaller rack. The largest piece of gear I used was a .5 C4 and even those were too large for much of the finger crack. Plenty of great rests to stop and plan your next moves though. Awesome route!!

WOW. Climb it!

So much fun. The platform below the anchors has nice patina flakes to bracket the rope when you rap, so use them to avoid adding your rope to the others stuck in the jaws of the crack to the left.

Felt easier than Bloody Fingers, but this is more steep jugs/crack technique, whereas BF is more slab techniques.

awesome climb with mostly thin gear for the majority. steep gym climbing to technical thin climbing.

Amazing. I felt like it was MUCH easier than Bloody Fingers, but it depends on your style. Super fun, totally a must-do for any City tradster.

Amazing and totally G-rated with a standard rack. This thing eats nuts. I was worried about using my finger-sized cams and conserved them after reading the beta that doubles are recommended, and I never ended up even using them. The beta about rappelling this route and swinging over to climber's right to wrap the rope around the nice rock horn to keep the rope out of the crack is spot on.
