Hello everybody I have witnessed a rise of interest in underground exploration lately on this site so thought I would add a new thread in ! My idea was at first one picture then realised it’s not possible lol ! So I came up with the idea your top 3 ungrounded pictures you have ever taken you don’t have to list where their at if it’s extremely sensitive I understand the protection people have on these sites as they don’t want to see them get ruined hope this thread is welcomed ! They don’t have to be a mine can be anything underground !
