Mine Day: UV Light Prospecting Mine Tours

August 20, 2022 @ 10:00 am – 11:45 am

Experience the 1845 Bevans Mine in a whole new light — by black light! Discover a world of minerals that fluoresce (glow) when exposed to ultraviolet light, including the young speleothems forming on the walls and ceilings of a mine typical of the Driftless Area’s Upper Mississippi Valley mining district!
