Half-deluged gold mining adit
I have found a short depression at one of minor gold mining areas, with a black narrow hole underground on it's end. The entrance was low because of loam fallen from slope above it, but after this place was high enough half-deluged adit. There were remins of tiny wooden raft, so someone probably tried exploring it before, but I did not have necessary equipment, so I just remembered the place and left it.
