You mean the entrance to Brownstone Mine I used has been closed after I used it this year? If so I'm not sure how they would close it off other then to blast it shut or take the ladder down.
The 1500 foot level you speak of I assume is zero level. That main adit is indeed blasted shut although if you go up to the rock air is roaring through it so the door you speak of in there must be open.
The entrance I found also had air roaring out of it.
Although it's incomplete many of the photos from Brownstone Mine can be found in
Week 13I also have lots of videos from inside the mine but it will probably take me awhile to do anything with them since I have to first learn how to edit videos.
I'd love it if we could get a 3D map of Wheeler Ridge with the Pine Creek tunnels in it.
