Counted from the 195 climbs here that carry a grade. Shown only where there are at least 5 of them — below that the shape is noise.

How well located

Base placed (one source) 14 Position on wall known 108 Crag only 76

The order of the climbs along this wall is known from the open catalogue, so a few surveys go a long way: standing at Sleven, Kook Slams (Boulder Portion), Papa Johnny (3 climbs, about 90 seconds on Nomad's Cave Bouldering) would place up to 11 more climbs between them. Survey the wall →

“Up to” because the estimate between two surveyed routes is only used when they turn out to be close enough together on the ground.

Rock, from the geologic map

Felsic gneiss. Paleoproterozoic, about 2,500 to 1,600 million years old.

Light-colored gneiss characterized by a predominance of quartz and feldspar. Biotite commonly forms less than 10 percent of the rock. Interlayered biotite-gneiss, hornblende gneiss, or amphibolite are locally abundant. Locally contains abundant sillimanite (20 to 30 percent of the rock).

This is the map unit under this crag's map point, read from the 1:100,000 sheet (Trimble and others, 2003, U.S. Geological Survey Geologic Investigations Series I-856-H). The point can be a few hundred metres from the rock, a cliff often stands on the line between two units, and at that scale a line on the map is about 100 m wide on the ground, so the wall itself may be the neighbouring unit. The rock named at the top of this page comes from the public geology of this area; this card is the map's answer. Every crag on this unit: Felsic gneiss.
