Glen's Crack

Either start from the bottom of the seam, or make a couple of delicate face moves (5.8?) to gain the right-trending seam. after 25 feet or so, step right into the next seam over. Angle eases after 30 or 40 feet. Continue up the seam to the chossy headwall with brown patina plates to a ledge with a two-bolt rap station.

This is the seam about 6 feet left of Jack, which is the left-facing corner above and to the left of the obvious roof.

Very sparse pro for the first 30 feet or so, which includes the crux. Probably some moves at 7 or 8 at the start. Be a confident 5.8 leader if you're going to lead this, and take thin gear and small nuts.

This route and Jack can be toproped by climbing

Irish Toothache

(which climbs right up the arete on the horizon at the left of the photo) and traversing right to achieve the ledge where the rap rings are for this route.

Toproping with a 60 meter rope will require some easy downclimbing unless you extend the anchor about five feet.
