For those who have climbed at the Bold and Beautiful Crag in Montagu, you will have noticed that the crag needs a 'base build' and the path to the crag requires work in order to stop erosion.

I'm looking for suggestions on how best to build up the base of the crag and stop erosion whilst giving a good platform to belay from.

The base of the crag is at a +- 45 degree angle, mostly sandy with few rocks to use.

Materials at my disposal: gum poles and metal stakes - poles could also be bolted onto the base of the crag.

Thanks in advance,
Justin

Gabions may be a bit expensive, but would probably work best if I understand your description? Gabion cages should be available in hardware stores (maybe not in Montague?)

(Gabions are mesh-wire boxes that should be filled with loose rock - should this be available - use this to build a retaining wall and then backfill behind it).

I had thought of gabions, however... I forgot to mention that there are no rocks around (to fill the gabions with).

One option I have thought of is to create a box up against the crag wall (the crag making up the one side of the box) using gum poles and shovel the sand down into it.
The only potential problem with this is that we will have to go all the way up to the top of the crag!!

On the path between Hallucinogen Wall & Superbowl we used a pole on the downward slope side propped up with threaded rods (sometimes drilled, sometimes planted), then covered with mesh, thow in big rocks, smaller rocks, sand etc. It has held up well.
