In reply to icnoble:
I was approaching the summit of Arant Haw (Howgills - GR SD 662 946) this evening, when I saw a large structure in my head torch beam. Funny, I thought, I don't remember a cairn here. It's the igloo! Proper entrance tunnel, room for four inside, needs a bit of work filling up all the cracks. Good to get out of the biting wind for a while. I took some pics - I'll try and figure out how to upload them.
