Generally great grid, but suggest you allow volcano for mount group, as these are all well known as that!

Good easy grid - uncle link has been used quite a few time before. Thanks for posting.

Agree with Jeannie. Also, as 'Mounts' Fuji and Olympus fit in both categories.

If the connection is just “Mount” there are two interchangeable solutions with crossed and fully interchangeable red herrings - if the connection is volcano there is only one solution - that’s actually how I solved it - so I’d tend to agree - Volcano has to be the connection and mounts should not really be allowed.

Otherwise a very satisfying grid

Did not accept Uncle or Mt

I'm awarding myself confetti for putting volcanoes!
