Hi Mark, Ben is finishing up with the guide to Twin Towers. The retro claims have been collected and it looks like Philippe Osborne did Anniversary Arete and Remembrance Arete in 2011 along with a few of the boulder problems. Once we've ironed out the details the topo will appear on Unknown Stones.
The topo for High Crags is here:

The leaning unclimbed arete at High Crags will be mega. It felt nails when we tried it but connies weren't good and we'd just brushed some wet lichen off it so it wasn't really in climable nick.
Burn Stones doesn't really warrant a topo yet, though hopefully it will one day. I think some of the strong lads have designs on the Midnight Oil roof from none jump starts. In the meantime you can find what's been done on UKC.
