I do have a guide for Qwantani albeit unfinished. After a 4 month stint off climbing due to broken toe I didn't get a chance to put it together and there are several problems missing that some of the local guys opened.
The first area which we opened (we thought of many) happened to be the only area without really sandy rock. There are probably forty or fifty documented problems in the area.
Depending on what grades you climb you can have several days worth of decent climbing.
The guide is too large to email so give me a shout on email@example.com
to arrange to collect.
