At 2.2m high and from 5 to 50m in length, the bottom tier of rough hewn basalt is generally traversed - but some choose to set hard diagonal rising mini routes with sit starts. It's likely that some people wouldn't appreciate the chalk patina that develops over the drier months and no one is really sure how the activity is viewed amongst Library management so please stay away from the front entrance area. The Lakeside walls are fantastic on a summers afternoon when the easterly breeze arrives.

Directly above Parkes Way as it tunnels under the ANU is the Noel Butlin Archives Centre - just outside this, on the north eastern side is a long cemented basalt retaining wall that offers a sustained traverse or if you are really sure about youself, some highball solo's ... be careful, little bits of render give way quite suddenly. To access it ride or walk there via the east/west lake cycle path. It is just off the path on the very steep pinch as it goes over the Acton Peninsular.

On the lake side of the Le Couteur Building, Research School of Physical Sciences, ANU, is a high retaining wall - one of the first built structures climbed in the ACT. It has largely been forgotten but it is still there with the same hard edgy problems which are much more accessible now that the ivy has been stripped away. Do your part - climb and prune!

Update: This wall has been torn down in the 2010-11 renovations of the area.

The side wall of the Torrens shops is a good bet for those on the south side. There was more of the same - an earth retaining wall below the old servo adjacent, but a rain storm collapsed it.
