Just left of Southwest Arête, use small edges to reach the top and pull over. Ament managed this with one arm.
2. Southwest Arête V3 ... FA: Jim Holloway, 1975 *
Climb the outstanding and obvious arête on the southwest corner of the upper boulder.
3. Drill Pig V? ... FA: Jim Holloway, 1976
Just right of the arête is this lesser-known and possibly unrepeated Holloway problem that ascends the south face right of the arête. Probably begin with a bad left hand crimp and small right hand mono. From there, go straight for the top without the benefit of the arête. It is rumored that Charlie Bentley repeated this problem, although shortly thereafter he failed to repeat the magic. Variation #1 - Drill Baby Drill V7: A variation to the above problem that starts and finishes in the same place, but does the hard move with the benefit of a left foot/heel scum around the arête.
Ascend this thought-provoking slippery problem located almost behind the tree on the lower boulder. A lower start that begins down and right near the start for #6 and surfs up and left adds a bit of worthwhile fun.
6. West Face V1 ... FA: Unknown
Above the steps is a good sidepull edge. Climb to the top from there.
7. Southwest Face V1 ... FA: Unknown
Just right of the last problem, reach high for starting holds, do some fancy footwork to get established on the wall and go to the top.
10. Southern Bulge V2 / V4/5 ... FA: Unknown *
11. Southern Sun V8 sds ... FA: Justin Jaeger, 2004
Do #10 from a burly awkward sds on opposing sidepull/undercling crimps. The crux is awkwardly positioning your body so you can pull your ass off the pads.
12. East Side Lower Traverse VB ... FA: Unknown *
Traverse right on jugs across the east face of the lower boulder. Finish up the arête with #14. Variation #1 - The Four Directions V4/5: A complete counter-clockwise circumnavigation of both North Rocks boulders done by Peter Jones in 1999/2000. Begin traversing with #12, but instead of topping out #12, continue around the corner and across #15. Where #15 tops out, continue around the uphill boulder's sloping section and traverse down the west face of both boulders, all the way until you arrive at the topout holds for #10 and pull over. A surprising and sequential crux happens rounding the corner at #2.
13. East Face of Lower Block V0 ... FA: Unknown
Start at a jug and ascend the center of the east face to the top.
15. East Side Upper Traverse V2 ... FA: Unknown
Traverse left to right 20 feet across the heavily cobbled east face of the upper boulder. Don’t stop until you pull around the bulging corner on the right and end up on top.
