An easy crack with many variations; the farther left (and thus the later you rejoin the crack itself), the harder and more esthetic it gets; from V0+ to V2-

The OW

Corridor Problem

Whale Belly

Hito

Left of the Corridor Problem

Hita

Jita Dyno

Start standing with left hand in a slot and right hand in an undercling at about shoulder level. Smear feet and jump to a knob just over the lip directly above. Mantle. 

  Exists also as an alternative finish for Jita which increases the difficulty.

The obvious steep OW, from a low start.

 This is problem I1 from the Mayer & Moret online guide.

One of the stand outs of the U-Mound area. 

  Start matched on the left facing edge/jug at shoulder level. Pull up to a sloper with a thumb catch up and right. From here there are at least 3 ways to do the next bit all of which are about the same grade depending on what you are best at. You can back step either way and reach up to either of the side by side edges with one hand or the other or you can heal hook by your left hand and rock up to the edges. Next make a difficult pull to the knob edge out right then up to another small edge and finally a bigger one. The holds for the top out are pretty small so if you don't scope it out first there could be some groveling involved...there maybe groveling anyway.

Nice compression moves with a potentially bad landing and a difficult top out, oh yeah and steep for the U-mound.

 Start from a sit with a low right side pull and an OK left edge. Heal hook right and pull up to a higher sidepull then stab at a higher edge with the left, the sooner you get to the good left hold the better. Another heel hook and reach high and right into the OW for an edge. Then start trying to find holds on the slab and still see your feet.

 This is problem I 0.5 from Mayer & Moret overview map. From their online guide, "Just left of the chimney is a very cool problem with a crack for the left hand and slippery sidepull rail for the right. Not the best landing, but Andy survived a fall from the top (missing the    crash-pad of course).  :) V5"  

Not sure which is Hito and Hita so if I have this wrong let me know. 

  This problem starts on the same hold as the Corridor Problem and makes a big move up and left to a small 3 finger edge (the right hand starting hold of the V3) with the left. This move requires practice to get the acurracy down to hit. Get your feet up and jump for a sloping ball with the right, there area couple of ways to do this. Top out as for the V3.

The real crux of this problem is convincing yourself that those start holds are even usable. 

  Start on a wierd slopy left handed pinch below the right facing corner over head and a right hand 3 finger gaston. These holds will not feel very good until you put your right foot on the starting hold of the Corridor Problem. Now hoist up into the right facing corner and match with difficulty. Bring your feet in under you and scum your way over onto the slab.

Would be way better if that darn boulder was not below it, not to mention longer. OH well. 

  Start laying down on the boulder below the steep wall. Both hands in a juggy slot in the horizontal crack/seam. Work your way right using a hold below the seam, crimps and slopers in the seam and heal hooks. Many different ways to sequence this. Eventually you will finish up the V3 right facing corner. There are again several different ways to make the transition into the corner as well.

A nice, sheltered corridor running north-south, with a few excellent problems. The ones in the corridor itself are pretty much all hard - V6 and up (except apparently there's a V3+ hiding in the middle - see problem description by LeeAB). There are several closely-spaced easy/moderate problems at the north exit of the corridor, on the west side.

 This is Boulder I on the Mayer & Moret overview map, although the problem descriptions vary a bit.
