Very weird…yet very interesting. not sure if it’s an old mining tunnel or is it a railway tunnel. I followed the old trail that was once tracks along the road…but lost it when it crossed the river…So only way to access it…is probably a mile or two back and cross the river…or the other side of this tunnel…wonder if this leads to Moria…lol (who gets it). Anyway…thats some extreme #UrbEx there…not something to do solo…#WheresNate #IdahoBound
