My usual plea for help in understanding a clue. Irregular mass of ice blocks one in Chamonix. I have u?e?e?. So uneven is irregular. Un is one in Chamonix. But how does the mass of ice and even get together.
I feel so feeble still needing help but there we are. I do!

Hi Steven, hope you're keeping well?

Uneven - 'neve' (mass of ice, blocks) 'un' ("one" from Chamonix)

I am very well thank you sir. I hope you are too.
Neve is new word for me but obviously one to file away in my developing crossword list.
As ever sir I am very grateful to you. You are so generous in your support!

I'm well thanks & happy to help - never "feel feeble", we all have days when an answer simply won't click for us :-)
