Dive test for the Kuurmanpohja mine. On the surface a light precipitate with a visibility of 0.2 to 3m in under 10. 10-15m do not even own hands. 15-20m visibility 2-3m. A white precipitate in water that is deep in the depths and on the bottom of the black sour cherry, which smells on the dripping egg. At the bottom 20m depths were found. The bottom has a fun-looking frosting in rock white and black. The dive had a sci-fi atmosphere when it had to go very slowly. http://kansalaisen.karttapaikka.fi/linkki?scale=16000&text=Kuurmanpohjan+kaivos&srs=EPSG%3A3067&y=6772442&x=592589&lang=fi
