New mine video channel. https://www.youtube.com/channel/UCxhNU-gNyPq2lXA7JhLB90Q The Sapphire mine tunnel is 2 miles long and is the main level of this multilevel mine complex. The mine features several natural caves and is wet. The main entrance to the tunnel was closed years ago. We first attempted access from the lower levels up the shaft but the ladders became too rotten, right before we were to head home, and the sun was setting we discovered a back entrance to the sapphire level. I made a quick solo go of it and explored most of the main level in about 45 minutes. It took a week to get this video together
