Saw something a few days ago, think it was on 'the sky at night'. They were talking about a small hill or something with a hole on top of it (most of the time). I forgot what's it's called, so does anyone know ?

Hi x303
I think they were talking about mounds and there are a group of them which appear to have depressions in the centre (except for one which had no depression). I can't remember where on the Moon these mounds are so will have to watch the Sky at Night again and write down the position of the mounds.

They were talking about volcanic mounds and if I remember correctly they were in the Hortensius-Milichius region.
This
might be useful too.

Thanks. They were talking about mounds or lunar domes.
Moonzoo doesn't include a tool to record these correctly, btw ?! Just the normal box set as 'other'.

I must have been on the sky at night, too difficult for stargazing live

Maybe they're Volcanoes?
