I was out with Nettle today on Creag Coire an Dothaidh, Bridge of Orchy. We climbed Salamander Gully as it looked in and neither of us had climbed it before.
The ice in the bottom 70m was thin and required care. The top section was more solid and gave good climbing, but probably a little harder than if more fully formed.
Turf is solid in the coire, snow is soft and unconsolidated, ice is forming, but mostly requires a bit of thaw and a refreeze (i.e. Fahreheit 451 isn’t formed).
It was below freezing in the coire all day, there was a light fall of snow for a couple of hours and hardly any wind (no significant cornices forming).
