Yep, thanks Rogissimo,
I'd stupidly been trying to use the first three letters of the river instead of the second - as the clue clearly state 😡Glad you got the others sorted.
Hi Jono,
It's the second half of a 6 letter river followed by a 3 letter "critical" - the answer isn't in Chambers but once you see it you'll be in no doubt what kind of "cross" it is.
Well done Kat, it's a great puzzle and well worth sticking with:-)
