I know it's mentioned already but I figured I would put it in the database in case anyone wants to try it in the future.  Start sitting with a left hand undercling (a foot off the ground) and a right side pull.  Use a tiny crystal way out right for the right foot and a good left foot below your left hand undercling (helps to be flexable).  Throw left to a gaston/sloper, right to another side pull, then the crux (for me).  It's unweighting your right foot long enough to bump it to the good foot just like 3 feet away.  Then your at the stand start V5. It's just that you have so much freaking tension on that foot, and no I have not sent it yet.

Easy Face

Just uphill from Extension wall, past Verdon Face and the next downclimbable dihedral is Pete's Gritstone Wall (PGW), which faces west.  The V5 version starts on low sloping laybacks and pops above the lip to some slightly more positive holds and a thin pocket and edge topout. A sit down start goes at V10. I can only imagine the low start going with cold weather, maximum friction, insane body control and sloper power. Highly recommend the stand up line, but it also is much more friendly in colder conditions (shady morning - midday depending on season).

This is probably the tallest line on the rock but is still somewhat obscure.  Start between Sunshine and the main V3 up the middle (west face) and crank for the deep 2-3 finger pocket with your right hand.  The problem goes straight up from here on small holds (a left sidepull high in the seam), ending up at a bad pinch on the right arete, from which you must throw all the way to the top of the boulder.  The pinch has deteriorated over time but the move still goes.

Bring lots of pads and spotters.

This is on the center bit of the south face, around the right from the SW arete (Sunshine). Climb on juggy slopers and edges left of crack up the middle of the face. I'd discourage moving right to the crack as you will discover hollow sounding loose flakes and rocks. Watch for some smaller friable edges and make some nice long reaches.

A great balancy top out on the left side of Extension Boulder, only one easy line is further left. Not as scary or high as the West Face, but more technical.  Start on the good layback at chest height (or the edges at waist height to add some more punch).  Don't miss the shallow two finger pocket or any useful edges.  The delicate body twist near the top is not to be missed.  Careful of loose rocks just back from the mantel topout.

About 15 yards right (south) of the Extension Wall proper and maybe 10 yeards right of Pete's Gritstone Wall (the V5 or V10 sds problem just right of the descent dihedral) is a rounded arete capped by a small overhang on the left. Just right of the arete, look for a good starting flake.

From the good starting hold, climb the southwest face straight to the top ledge about 16 feet up. Use good edges down low, a thin horizontal seam, a sloping layaway and maybe a pocket up high to latch the top ledges and pull over. Pretty casual fun.

Climb jugs and edges to the left of Sunshine up to the obvious four inch wide pocket at half of the wall's height. Move right from the pocket to the juggy ledge on the SW arete. Either find a sidepull two feet right at the same level as the ledge hold and pull right of the SW arete and up, or make a long reach straight up (harder) and exit up.

About 15 yards right (south) of the Extension Wall proper and maybe 10 yeards right of Pete's Gritstone Wall (the V5 or V10 sds problem just right of the descent dihedral) is a rounded arete capped by a small overhang on the left. About eight feet left of the arete, look for good starting flakes on the west-facing wall followed by a secton that may initially look blank.

Start on the good flakes and pull up and slightly right on progressively thinner holds. When it seems like you can go no further, high-step and a long reach to an incut edge becomes possible. From there, pass the "spooky tooth" and use slopers and jams under the overhang to reach for the right side of the overhanging top. Pull over the 20' topout is balancy, but reasonable. All in all, a pretty fun problem.

Classic highball up the center of the West face.  Several starts exist to gain pebbly holds in a seam above head height in the middle of the face.  Above this you'll find two of the most amazing big pockets ever.  Two options from here: 1) use very small intermediate two finger pocket and/or edges to reach the big key right hand layback several feet above, or 2) make a big throw from the big pockets straight up to the layback. Now the really scary part, holding it together through more layback moves and the 19 foot topout.

This is a superb line of crimps on the S arete.  Sit start on the corner (starting on the crimps left of or directly on the corner are about the same difficulty).  Fire the line of crimps directly above including a big throw to a shelfy jug on the arete.  Top out from here (up or directly right and up both go).  Be sure to cover the small rocks quite a ways back from the wall since flying climbers come a long way out when they miss the throw.

A fine traverse from a sit start on the south arete moving low across the face topping out on Rocky Top.  Great variety in the moves and holds (from pebbly and edgy crimps to a deep pocket).  The crux comes within the first 15 feet passing the bulge.  Relatively restful moves across the pod in the center of the face lead to interesting reaches and cross throughs with small feet.  Exit via the balancy moves of Rocky Top.

The farthest left independent line on the West Face of Extension Wall, just left of Rocky Top is this easy face.  Pull up on dual jugs and either use the seam hold or skip it to reach to the next jug. Hit the top and mantel, being careful of the loose rock above the top.
