Routes as boulder in United States

An iconic Red Rocks boulder problem. Crouch with small but incut crimps and climb directly to the lip, and mantle above.

Sit start with big flakes, follow the lip up and right to the apex of the overhang. Top out.

Harder now due to breaks on the topout holds.

Start: On either side of the obvious arete that creates the left side of Cat Corner. Go: Up the left side of the arete to the top. (If you start on the right side, make an initial hard move to gain the left side of the arete.)

Tricky start, then easy.

Chimney

Ultra classic traverse from left to right. The best way to get pumped in Joshua Tree. Don’t sit down at the rest for more than thirty seconds!!

Start: Just right of the Ratraverse bulge, underneath the obvious right-pointing horn. Go: Climb up to the horn and then over to the top.

It is on the obvious boulder on the corner facing the VA parking lot and the Jefferson Playground. This is a short, little, slab problem to warm up upon. You either have to down-climb the slab or down-climb the back, which may actually be a harder problem. You may need a bouldering pad.

The crack on the right side of the small cave on the uphill face of the boulder.

Handy descent for the Pegboard Wall.

The right-most crack on the boulder.

This may be the same problem as previous (Steep face).

Mega classic right of tree on downhill side of the boulder. Reachy stand start and follow the easiest line to the top. Crouch start is (height-dependent) V2.

The obvious layback in the centre of the wall. Sit start is V2.

The pleasant white slab on the left side of the front face of the main rock. Has at least 3 different independent lines, all about the same grade.

This is the main, ladder-like route to the right of the middle of the big rock.

Midnight Lightning is a problem on the Columbia Boulder in Camp 4 of Yosemite National Park. It has been described as the world's most famous bouldering problem.The route had been easily identified by a chalk lightning bolt drawn by John Bachar in 1978 while attempting the problem with John Yablonski and Ron Kauk. In May 2013, the iconic chalk lightning bolt was scrubbed off the face of the boulder. The bolt was re-drawn in the same location a few days later.

Between the Arete and Centre. Sidepulls or crack down right to start, then up through delicate techy feet and shallow edges.

A mega classic of the area. Quite tall with a high crux and a nicely placed boulder to break yourself on right in the landing. Bring a few pads and spotters.

Up the shallow corner just left of Overhanging Lieback, using it as needed.

The offwidth crack that can be face climbed.

Stand start (V2/V3), climb the right arete until it is possible to use the left lip. Top out at the apex. Precarious and commiting. There are a couple of sit start options: with both hands on the arete adds little difficulty, starting with a sidepull undercling feature just left and moving to the arete is V4. A variation (V2) exits right into the small dihedral above the start.

Must do! Great pockets and great big crown at top...hug it!

The obvious low roof opposite the corridor.

The thin face in the middle of the uphill side of the boulder.

From the large heuco, can also traverse left on jugs and downclimb the start of Embryonic Journey.

There are numerous classic variants on this panel of rock - ask a local for some pointers!

From the bottom of the diagonal ramp, climb up through the obvious undercling to the top. Watch for poison oak down low.

Start: At the tallest, steepest section of the eastern face, find an obvious, large right-facing flake that archs up right. Go: Move up the flake until you can reach out left and gain the long hand rail. Move left and down along the rail until decent holds allow you to climb straight up. (Traditionally done with a heel hook.)

Up obvious vertical crack on far left of wall.

Take care not to damage the ferns.

Traverse from far right to left arete and top out.
