Hi Scott,
If you are looking for a bolted abseil line off Bluff Knoll, there ain’t no such monster. There was a minor war years ago about bolts on Bluff Knoll and it has been declared a Department specified no-bolting zone so a commercial operator who put in a bolted abseil line would not be given permits to use it.
The old CAWA guide has some Stirlings info including Bluff Knoll. We give them away free to new members if they turn up at gym crashes or the like.
Cheers,
Toc.
