So i went to the Boneyard on the weekend and it was an eye opener, why didn't i go there sooner!
The rock quality is superb. The climbing even better.
If you can climb grade 24 i would advise going there as soon as you can. (The cliff will be closed from Aug to Dec)
Gerry Narkowicz has put together most of the information for this area on his blog.
