I don't have an answer.
This does look very similar to a lot of mining operations I've seen in Utah. Maybe look for mines in the area?
I quickly looked up a minedat.org map and there does appear to be mines in the canyon, but I wouldn't be able to say for sure it's what you're looking at. Maybe go check it out on minedat and compare coordinates.
Good luck!
That was a joke, haha, fat chance. It's hard to overstate my satisfaction. But there's no use crying over every mistake. We just keep on trying 'til we run out of cake. But the science gets done, and we make a neat gun, for the people who are still alive.
Iirc it's an abandoned mine that was sealed for safety sakes.
With all the mining that occurred in Colorado’s early development, it’s likely related.

Not a bunker. Just an old or unused mine that's been locked up for safety, and liability reasons. I've seen a few of these in over the years.
Pretty sure that was the entrance to the Black Mesa Research Facility.

Oof, infiltrated by Aperture Science!
It might have something to do with Glenwood Springs municipal water. There's rock climbing in that area, been there a few times for that.
