Eccentrically twisted helictites, cave pearls polished to a high luster, satin-petalled cave flowers, showerheads that mimic the real thing, moonmilk (the gnome's milk of ancient medicine)--all of these and many more are described and illustrated with over 250 full color photos in this all-new second edition. This book is dedicated to everyone enchanted by the delicate beauty and diversity found in the underground wilderness all over the world.
