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 about 500 feet inside the lower adit facing a splitoff in the ore cart tracks.  A large rusted metal water tank about 15 feet in length, five feet in height, & two feet wide occupies the side passage.  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.
