Neil and I went to the Wst Face of Aonach Dubh to do B to F route on Saturday. This scramble ascends the buttress to the right of Dinnertime Buttress and traverses across the middle ledge (the fault line between the andesite and rhyolite layers) to No. 4 Gully. A shallow rib allows the gully to be climbed to the upper ledge where you can keep to the crest of F buttress or double back across towards Dinnertime to escape. From there we carried on over Stob Coire nan Lochain and Bidean before descending by Coire nam Beith. The exposure on middle ledge alone is worth doing this scramble for. Its never difficult but feels a really wild place to be. Its been a moslty dry week here in lochaber and has warmed up a little since last weeks dusting of snow so there's still plenty of mountaineering to be done before winter arrives!
