Lois Manno's "Visions Underground"

Female Caver and author, Lois Manno, offers her book "Visions Underground" in the NSS bookstore. It traces the history of the artists and photographers who have explored the awe-inspiring forms and colors in one of the most extensive cavern systems in the world. The book includes images from the first caver/artist to capture the cave's mysteries in oil and canvas, to contemporary, surrealistic, photographs of cave pearls, soda straws, and pristine pools of blue-green water.
