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.
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.

What a sweet crack up high. I think the grade is right on. It is a safer lead than Bloody Fingers (seen some crazy liebacks on the start to BF), but not more or less hard.

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.
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.
