Routes as trad in Thorn Buttress

Start: The ragged corner 10M right of the blackberry filled gully.

Straight up the layback flake to the chains (or beyond).

Mixed pro.

Bolts L of Gladiator, stepping into that route to finish.

Takes the overhanging line just left of the corner (marked). Climb through the overhanging start (crux) to a stance just under a small roof, then reach out right and climb into the opposing corner. Continue up the line to a layback finish and chains.

Takes the poor-looking rock immediately left of the marked Olympus start, joining the upper corner via a reachy and powerful sequence. Was the original line until the loss of some holds.

Rarely done, mainly because it has a sport (bolted) start, then relies on trad (small wires) to finish. Climbs Pussycats start (crux) then trends left into Kiss My Brain (bolt and old piton). Over roof, but instead of taking the bolt line left (KMB), go up 2/3m then trent left to arete. Finish at top chain for maximum enjoyment.

The good-looking corner crack just right of 'Sardine'. Cruxy start, then once level with Sardine's 2nd bolt, it eases off (but not completely). Best finished by traversing left to the 'Sardine' chains.

A really good combo route. Start as for Terrethea, but prior to its crux reach out right for the big flake of 'Terra Incognita'. Match this and continue up the line. Effectively dismisses the original 'Terra Incognita' reachy crux.

Take 'Japetus' to the 'hole' - then launch up the left side of the arete past a small edge and a 'hidden' sidepull to the 'Japetus' break.

The original line continued up the face of 'Terra Incognita' - however cutting back right at the good rest and launching up the direct finish of 'Japetus' Direct makes for a far better route.

The original route. Now superseded by the direct finish.

Start: Takes the very overhanging arete from its base up to the 'hole', then tacts right around the steep arete and up to the big break via a good undercling. This original line then stepped left and finished up the 'Terra Incognita' face.

A boulder problem traverse link up into Japetus Direct Finish. Start (sit) left of base of Olympus - dyno rightwards and climb across cave to juggy traverse that leads underneath Sardine etc to base of Japetus. Continue up that route. Best done with a top-rope clipped in prior to embarking on the route itself. Basically a V5/6 problem into an existing 23.
