Did you know?

Did you know that you can create an account to record, track and share your climbing ascents? Thousands of climbers are already doing this.


The area near to the radar array itself. This sector comprises the high parts of the hill to the left of the Tombstones when you look up the hill from the base. As you head north, it's everything before the broken fence which looks electrified but is broken in many places.

Access issues inherited from Radar Range

This crag is on private property owned by the Harden Council. The Council has been approached and has advised that anyone entering this area does so completely at their own risk - you break it, you're on your own. There are a number of land users, including people who walk and ride up the hill, and nearby farming land as well as the Air Services Australia owned radar at the top of the hill.

Please be sensitive to potential issues and don't make noise that's going to arouse interest (you will be heard for a long distance). Don't expect to always be alone. Please note the ethics - they are there for good reasons and it's all about keeping this crag open, not styles of climbing.

Do not approach the radar array please. For any reason. Be sure to close the gate. Every time. Don't expect someone to close it behind you, you may let some cattle in or out in the meanwhile. Please stay away from the very obviously fenced farmer's land. There's enough boulders to climb without venturing over there.


If you park at the top you are metres away from some established climbs, downhill.

Ethic inherited from Radar Range

NO BOLTING AT ALL - not even for setting up top ropes or cleaning, thanks. Use some gear or sling a nearby boulder.

NO CHIPPING OR COMFORTISING - there are WAY MORE than enough problems here! However, please do make the effort to clean off flakes that are likely to go, and moss.

KEEP THE BOULDERS CLEAN - this means removing tick marks and cleaning off excess chalk if need be. Vinegar is great for removing chalk and the granite won't be affected if you need to give something a scrub.

Finally, please follow the naming conventions. Climbs have been named in a satirical fashion. If you make a first ascent - and there's every likelihood you will, given the massive boulder field - then go ahead and have a go at something that amuses or annoys you. Do not number your climb. Give it a frickin' name. Feel free to explain what the name means in the description.

Variants and eliminates welcome. It is bouldering, after all.

V0 to V1 Paddy Got Potatoes Boulder 4m

Looks easy, doesn't it? Then you realise it's stacked hand and fists to start, with a lovely drop onto a hard granite slab if you do anything wrong, and the crack widens as you go, making it a full offwidth experience with the extra spice of possibly having to roll down a hill if you fall. Easy enough if you layback and avoid using the crack, but around V1 if you go at it full offwidth style.

FA: Ian Carter, 2012

Project 6 Boulder

Straight up the slab.

Project 5 Boulder

Follow the under/sidecling rail all the way up. Burly.

Project K Boulder

Straight up the overhung section of the boulder with holds facing mostly the wrong way. Gonna be hardish.

V0- Chicks Don't Fart Boulder

Up the easy crack with big jugs to help you out. Hard to fall out of!

FA: David Nott, 2012

US VB+ Myth Busted Boulder 4m

Up the chimney. Another one for the kids.

FA: David Nott, 2012

Project D Boulder
Project B Boulder

Sit start and up, cleaning as you go!

FA: Honza, 2013

US V0- One Heel One Slap Boulder 4m

Another warmup. Sit start.

FA: Ben Dacies, 2013

V5 YoungDumb Boulder Project 7m

Start from down low, huck a huge move out left to get started on the rail, feet are very poor, need a few spotters and mats to get this guy done. Not 7 metres tall, but about that long.

V3 Youngdumb the Shorter Boulder 5m

A longer traverse along the boulder but not the full deal.

V2 Poopsicles Boulder 5m

A shorter variant of the traverse for 'YoungDumb''. Start at the end of the boulder, traverse left until it starts becoming thin on feet and mantle up at a rail/pocket then finish via the easy slab.

FA: David Nott, 2013

Die Already Boulder

Extremely overhung (for granite) and likely to give someone a workout.

US V2 Nerd Rage Boulder 2m

Sit start the left side. Lovely topout. Not bad.

FA: David Nott, 2012

US V0 What You Need to Do Boulder 2m

Sit start the right side. Big jugs, goes easy enough.

FA: David Nott, 2012

US V1 Parkinsons Boulder 5m

Nice high slab with jugs to top out. Can't ask more than that.

FA: Ross Parkin, 2012

US V2 On The Phone Boulder 5m

Right of 'Parkinsons' but sharing some real estate. Mossy currently.

FA: Chris Maciejowski, 2012

US V0- Walk the Line Boulder 3m

Up through easy territory.

FA: Georgia Marjoribanks, 2012

US V1 Neener Boulder 4m

Slabbing again! Balancy but not hard.

FA: Tyron Ahern, 2012

US V2 Mace Boulder 4m

Up the body of the boulder. Techy feet.

FA: Chris Maciejowski, 2012

US V1 Cranium Check Boulder 5m

Stick to the arete as closely as possible and make your way to an interesting topout.

FA: Chris Maciejowski, 2012

US V0- Worth it? Maybe. Boulder 2m

Sit start on the attached flake, lay back using only it then go for the top.

FA: Christopher Lean, 2013

US V0- To the Loser, Spoils Boulder 2m

Sit start.

US V0- Snail Rail Boulder 3m

Sit start on the bottom of the rail moving up, try and use only the rail before moving to the top. Fun if you are waiting for a pad.

FA: Christopher Lean, 2013

US V1 Easy Way Out Boulder 4m

Start as high as possible and thereby avoid all the difficult stuff.

FA: Tyron Ahern, 2012

US V5 to V6 Lest We Forget / Miss You Old Man Boulder 4m

The low stand start to 'Easy Way Out' from the poor underclings. Up from a very hard move to top out from underclings onto the rail. You can move to the intermediate pinchy grip and it's about a 5 or pull yourself in close to the boulder and huck a big throw and it's a soft 6. The only climb I'm going to name here that doesn't have a satirical theme.

FA: David Nott, 2013

US V8 Undercling project 2 Boulder Project 4m

The sit start to 'Easy Way Out'. Unfortunately requires a few stacked mats to get going, so quite contrived. Very hard on the biceps - at virtually full reach, use the rail and poor underclings to get off the ground, then execute as per the harder variant of 'Lest We Forget'. Possibly one for the future generations...

US V4 Day Too Long Boulder 2m

A hard sit start from a side-cling with the left hand, incut for the right and a heel hook. Just leave your left foot dangling...

FA: David Nott, 2013


Up through easy and juggy holds.

FA: Ben Davies, 2012

US V0 Carry-On Boulder Boulder 4m

Up using the flake (hard to ignore, really) through easy and good holds.

FA: David Nott, 2012


Another easy one on this boulder.

FA: Ben Davies, 2012

US V2 to V3 Effafirey Boulder 4m

Bit height dependent as to the grade. Up through a compression move is closer to 3, or work to the high step first and it's more like 2. Good moves.

FA: David Nott, 2012

US V4 to V5 Dr Weevil Boulder 4m

Hard 4 or easier 5, bit difficult to say. Some balancy moves on small foot and hand holds will get you to a finish jug. If you have enough energy, execute.

FA: David Nott, 2013

US V5 Dodgy Rodge Boulder 3m

A hard sit-start using side clings/compressive holds to a much juggier top-out. Getting your feet under you won't be as easy at it looks, but it isn't the hard part.

FA: David Nott, 2012

US V2 Marvin Boulder 3m

Brain the size of a planet, and I'm stuck bouldering... Start holds are left hand sidecling and right hand pinch (sit start).

FA: David Nott, 2012

US V8 Falls to Ground Masturbating Boulder Project 5m

Needs gardening (removal of a boulder at the sit - full excavation, please don't use explosives much as you may wish to) before this can be sent. A granite, sit-start, CAVE problem. Yes, you start fully horizontal. Will be a hard one if someone puts in the work to clean up the sit area. Otherwise it's a fairly poor problem.

US V3 to V4 Bogan City Boulder 3m

take me down past a Bogan City, where the grass is green but the girls ain't pretty...

Grade depends on where you start. Lowest handholds are harder, adding a move or two to the problem. Originally more like 4-5 for the techy rockover topout on tiny holds, but one of the holds exploded making it easier! Two cruxes marked on topo to reflect position of starting holds depending on the difficulty - lower is harder.

FA: Ben Davies, 2012

V2 Just One Fix Boulder 3m

Right hand variant to 'Bogan City'. Sit start to the right using the pocket with your right hand and huck your way up.

FA: David Nott, 2013

US V0 * Booark! Jesus! Boulder 4m

A nice amble up an arete.

FA: Ben Davies, 2012

US V1 Booark! Whoops! Boulder 4m

Tackle the face of the boulder then top out up the arete.

FA: Ben Davies, 2012

US V0+ Booark! Mantle! Boulder 4m

Up through the face of the boulder left of 'Booark! Jesus!'. Looks very easy but there's not much there and the mantle is techy for the grade.

FA: Ben Davies, 2012

US VB- Prawn Boulder 3m

Put on your sandshoes and walk up the slab.

FA: David Nott, 2012

US VB- Bacon Eggsplosion Boulder 3m

Another one for the kids!

FA: Ben Davies, 2012

US V0 Gritty Gash Boulder 4m

Follow the arete avoiding getting into the crack. Top out on reasonable holds.

FA: David Nott, 2012

Middle Project Boulder 4m
V1 Snowjob Boulder 4m

Up through good holds to a fairly non-juggy topout!

FA: David Nott, 2012

US V3 Queen Laqueefa Boulder 3m

A sit start on good holds that goes into a technical rock-over on a tiny foothold. V3+ - hard to grade at the end of the day!

FA: David Nott, 2012

US V1 Free Hugs Boulder 4m

Up the crack.

FA: David Johnston, 2012

V3 to V4 Rush of Blood Boulder 6m

Up through small holds. Technical, using a thumb press/side cling. Easier version would be to head right at the break but you pretty much end up doing 'Second Marriage' and can give up a grade for it.

FA: Roscoe2, 2013

US V2 to V3 Second Marriage Boulder 4m

Requires a little commitment through the overlap. Small holds, but use the pocket for your feet and you'll get through.

FA: David Nott, 2012

Project AB Boulder
US V0- Wussburger Boulder 5m

Up and head right through big holds onto the ledge then up and over on good holds.

FA: Daniel McGlinchey, 2012

US V4 Project AC Boulder 5m

note - top needs cleaning, pretty dangerous as is with lots of loose flakes

Up using sideclings to a pocket and a poor rail, then up through small jugs with crap feet and top out.

Project AD Boulder

Up and into the scoop through very poor holds.

US V0- Layhack Boulder 4m

Up laybacking the flake with feet to the right then topout.

FA: David Nott, 2012

Project AE Boulder

Up and into the scoop through very poor holds.

Project AF Boulder

Climb the arete.

Project AG Boulder

Up the body of the boulder.

US V2 Mad Man Boulder 2m

Another lowball sit-start. Start right at the arete and throw to a rail for left hand, then up and over.

FA: David Nott, 2012

US V2 Madder Man Boulder 2m

Left variant of 'Mad Man'. Sit start the body of the boulder using compression and throw to the top then top out.

FA: David Nott, 2012

US V3 Stupid Man Boulder 2m

Eliminate. As for 'Mad Man', but keep feet above the slabby lower part of the boulder.

FA: David Nott, 2012

US V0- Another Walkup Boulder 3m

Walk up the side.

FA: Daniel McGlinchey, 2012

US V4 Halibumsis left Boulder Project
US V3 Halibumsis right Boulder 4m

Sit start. Up and right.

FA: David Nott, 2013
