>>862295Photo is by UER user Darkzero, he also runs the Facebook page British Columbia Ghost Mines which is probably the most complete resource online for abandoned mines in the province. I read the other day that he got that picture using "light painting" where you leave the exposure open for a few seconds and shine your flashlights over as much surface area in the cavern as possible before the shutter closes. Before I read that the only way I could imagine them getting much light into the mine was by hauling in high powered flood lights.
It's extremely difficult to take photos inside abandoned mines, it's the darkest dark you've ever seen, eyes wide open for half an hour straight and they won't adjust, just pure darkness in all directions. When I walked into that massive cavern the first time my stomach dropped to my fucking toes, the light from my dinky little automotive mechanic headlamp could barely reach the far walls. It's absolutely mind boggling to be there in person, exploring Carolin Mine is a vivid memory you will have for the rest of your life, it's an absolute MUST for any BC locals (but unfortunately it's active again and completely blocked off from public access for the time being).
>>862328I wish I knew. The picture is from the abandoned Greenhill Mine site in Blairmore, AB, taken earlier this month. I have seen mine buffs comment on those massive chains/tracks online before but I can't remember what they said.
