Topo Routes
2.11 Archimedes' Principle

"Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." Routes like this are why you travel for hours/days to get to the 'Grampians'. Often worked in 1 pitch from the ground. Start: Start under a low bolt at the base of the most impressive part of the wall. 1. 20m (22) Up past the bolt then R along a break to a semi-hanging belay. 2. 30m (26) The grey line of holds up the otherwise blank wall. Sucks up dozens of med-large wires. Often done on preplaced gear which probably drops a grade. 3. 10m (26) A little boulder problem around the roof past a bolt. Nobody seems to bother with this.

26 Mixed 60m, 2
2.14 Pythagoras' Theorem

a2 + b2 = c2. Prepare your groin for some hypotenuse action. The other ultra-classic line here. It's supposed to finish via the third pitch of "Darwin's Theory" but this is often ignored. Start: Start under the central corner. 1. 10m (20) Pocketed crack to ledge at base of corner. 2. 30m (26) The stemming corner, then move left and finish up the arete.

26 Mixed 50m, 3
2.1 Heisenburg's Uncertainty Principle

The position and momentum of this route can not be simultaneously determined. Not in the same class as the rest of the crag. The next crack left of Newton's Law, 3 metres left of Maxwell's Demon, move left at ledge and continue straight up.

2.2 Maxwell's Demon

A thought experiment intended to show that the 2nd Law of Thermodynamics has only a statistical certainty. Start 4m L of Newton's Law. Wall just R of easy crack to ledge, trend R up grooves.

2.3 Newton's Law

Noddy's physics need a brush up...there are three Newton's laws, not one! Start under the nice thin crack on the L side of the wall. A great thin crack to the walk-off ledge.

2.6 Darwin's Theory (1st 2 pitches)

Survival of the fittest. Described without the third pitch so that it gets noticed as a fantastic 2 pitch 18. Start: Start as for Newton's Law. 1. 30m (18) Up "Newton's Law" for 5m then R to the line of big white scooped out pockets. Up these (take slings for threads), then a piton for the finish to the break. 2. 25m (18) Hand traverse R along the rising break to the rap anchor above "Pythagoras' Theorem".

2.10 Archimedes Principle P1
2.13 Pythagoras' Theorem P1
2.19 Schrodinger's Cat

Kitty is simultaneously alive and dead ... until you look. Start 15m R of 'Pythagoras Theorem'. Short steep corner crack then L up ramp past bolt. Back R through overlap to 3 more bolts up the wall above.

25 Mixed 45m, 4
2.15 Ockham's Razor

"The simplest explanation or strategy tends to be the best one" This is a direct of the arête of Pythagoras' Theorem and was climbed as one long pitch. Start as for PT first pitch, at ledge clip first bolt and climb face between arête and corner. When level with first bolt move on to arête proper and follow this all the way to the top alcove. There is a tricky crux just before you join PT on the arête. 5 carrot bolts and trad.

2.12 Archimedes' Principle - Pythagoras' Theorem link

Climb Archimedes' Principle to belay of first pitch then continue along break to Pythagoras' Theorem. Either belay in corner or climb down to Pythagoras' Theorem first pitch ledge. Start: Start as for AP

22 Mixed 30m, 1
5.1 The Alkali Tide

Worth doing for the second pitch experience (not!). Start: Start under overhang at right end of wall. 1. 30m (16) Boulder the roof then up to ledge. Slither up through overhang. Up 1 metre right of faded guano streak. Up and past left end of grassy ledge (slings). Belay on arete. 2. 20m (1) Up.

2.7 Darwin's Theory pitch 3

Natural selection in action: nobody does this. Start: Start at the rap anchor above Pythagoras' Theorem.

2.8 Foucault's Pendulum

A great pitch that goes all on natural gear. Follow the first pitch of Darwin's 'Theory' to the second thread in the huecos (just below the piton). From the big thread, traverse out right across the weakness that is visible leading all the way across into Archimede's Principle, finishing as for that route.

2.4 Diminishing Returns (Top Half)

Start as for Darwin's Theory for 10m then blast straight up orange wall past very spaced bolts and finish up grey headwall.

2.9 Diminishing Returns

Needs a 60m rope!!!!!

27 Sport 30m
2.17 Pavlov's Dog

Start just left of SC. Amazing wall climb.

29 Sport 14
2.20 Vege Maths

Amazing line.Finishes at SC anchors.

25 Mixed 30m, 8
2.18 Cats & Dogs

Straightens out SC. Starts up SC, finishes up headwall of KP project.

28 Mixed 10
2.16 Project - Clean Cut Phil

Starts as per PT moving right at undercling flake. Moves into PD for 10m then weaves up incredible thin face.
