The Vernon Mine is a gold mine north of Yreka, California. I have not been able to find much information on this long abandoned mine. This was taken at the portal which has some collapsed beams as well as a partial entrance cave in. The lower adit crosscut goes in for about 1, 000 feet before reaching a dead end w/o reaching any quartz vein. There are a couple branching splits including one leading to a minor stope. As you zoom in to the interior of the tunnel one can see the white cloudiness of an actual ghost. Hah, well actually that is just a convergence of the outside cold air meeting w/ the interior stagnant warm air of the mine.
