Martin and i visited Coire an Lochain today and climbed Inventive on Number 1 buttress. The route starts up the Vent before breaking left. The ice bulge on the Vent is in good condition and Inventive had lots of good snow ice.
There are many buttress routes in condition at the moment in Coire an Lochain. Some of the cornices may be impassable. We walked out via Coire an-t Sneacdha. Amazingly,despite the thaw of the last few days, some of?the higher buttress routes on Fiacaill Buttress are complete. The plateau also still has excellent snowcover and from a distance it appears like there may be a few things to do on Carn Etchachan.
