Went out this evening to check out two cliffs for hidden caves. It's difficult to see whether there are any caves on the cliffs sometimes especially from either the top or the bottom and this means it's necessary to scramble around on them for a bit. Anyway, I didn't find any new ones but I do know where not to look in future. Looked around onto the front face of Common Cliff/Upper Blackhole Cliff. I rather think our guidebook has it wrong and the Upper Blackhole is 400m further westward. The cloud came in later on this evening. Grim weather forecast for tomorrow. Sunday's weather should be a little better.
