Climbed the SE ridge today on good frozen turf and rimed up rock. Coire bowl is quite well scoured, but slab formed in sheltered locations, with a bit of depth higher up. Girlfriend and a friend climbed Beinn Narnain from the N side, reported seeing a fair bit of slab as well, but were able to avoid all but the shallowest Snowing gently as we walked off
