I don't know why, but when I read the title I assumed the map was about landmines.

No, these are the cool ones that take stuff out of the ground, not the ones that destroy everything above them

Same! And then I saw three near my house and thought "if they know where they are, why haven't they been removed???"

Then I clicked on one and saw it was the name of our local rock quarry. :)

I'm pretty sure for me "mining.fyi" wouldn't have created any associations with landmines (although "mines.fyi" does seem to match the contents of the website closer).

It'd be really interesting to see A/B testing results about what most people associate the word "mines" with (I wouldn't be surprised if that would be landmines in this day and age).

Even "mine.fyi" would be better at not making me think "landmine", although that would instead get read as "belonging to me".fyi.

I assume this is probably because most people don't see mines (as in gold mines) mentioned in plural very often. Or if someone does refer to multiple mines at once, they usually also specify the type of mine at the same time, like, "the cadmium mines in [country]" or similar. Or if talking about old, abandoned mines in an area, they're usually referred to as such.

The word "mines" on its own without an adjective usually does mean landmines, I think.

(I also immediately assumed this was about landmines.)

Oh! I thought it was landmines too and was very confused + concerned when I saw dots near where I live.

hey now, landmines destroy stuff below them too

I had exactly the same thought, and was quite intrigued. Very disappointed actually, it would be cool if there was open data about land mines.

The US government has been pretty good about cleaning up the UXO it knows about, which means what's left is the UXO it doesn't know about. You'll find it near most of the current and former testing ranges, particularly Yuma Proving Ground where there's trails leading right from the adjacent BLM land into areas with potential UXO. The only real barriers are a few signs and the law.

Cleaned up on their own territory. UXO are still a danger in other countries, such as Laos.
