Well I checked the forum on my phone from the top picnic log and thus didn't bother trying to find abseil locations. First climb of the day was Possum 13 50m. Wandered off on what we guessed was the track down to South Buttress and thought we would come down coc-ers gully but as the track bent around the bottom of the cliff we recognised that we were in fact coming from the SW end of the crag, but were quickly able to recognise some climbs and wander along to possum.
Pretty tough moves getting off the ground, then a superb traverse on the second pitch, then some more tough moves getting around the hanging blade on the 3rd pitch. Thoroughly enjoyed though.
After lunch we had aspirations of heading out to the northern slabs to get on Denethor/Lepton, but unfortunately we did not recognise the climb as we walked past it, thinking we were still at the "Central slabs".
We then continued bashing our way along in the scrub, thinking we had arrived at the end of the "Central slabs" and were looking for the "Northern Slabs." We bashed along for quite a while before giving up and returning along the base of the cliffs. Still unable to recognise any features we were quite at sea.
Finally when we got back to Denethor the penny dropped and it all fell into place and we were able to locate ourselves relative to Northern slabs/the terrace/central slabs. However by this time we had run out of daylight to start a 4/5 pitch climb so we elected to walk out to the car and drive to Kambah rocks (my buddy has recently moved to canberra and wanted to check out the crag.)
Another extended walk (made somewhat longer because we assumed that the river was flowing in the opposite direction - the guidebook says to walk upstream) so after exploring the local nude bathing area (we looked very out of place, and we were, an experience I do not need to repeat) we finally set off in the right direction to find the crag. Got there right on dusk and got up The Bummer with my headtorch.
