Openings Into North Korean Mountain

These openings, and any opening into a hillside like this, is called an adit.

Your assumption is correct, this is not a mine. A mine would have larger adits, signs of heavy vehicle traffic, and a lot of equipment around the mine. This has all the hallmarks of an underground government/military facility.

Once again, thanks for the great information.

No problem. I look at this kind of stuff all day at work so I tend to notice things that others might not think of.

So you get paid to do what my wife gets mad at me for spending so much time doing. Great!

LOL! Yep, pretty much, although I'm not getting paid THAT much. I'm getting ready to retire from the Navy at the end of this year. I've got a job with a private company doing exactly what I'm doing for the Navy but for about 90% more money.

By the way, some of the commercial stuff you see here is almost as good as the government stuff I see at work. The big difference is the best stuff here is focused on the U.S. and the government stuff is focused everywhere BUT.
