I n the beginning, Discovery cave was a wild cave with no lights, no hand rails, and twisting trails that disappeared into the darkness. Cave guides with battery powered flashlights lead you down into the dark abyss, into the very bowels of the earth to see the underground splendor. First of all you're probably wondering what could be in the bowels of anything worth seeing, let alone walking into.
Stalagmites are the things that grow up.
Columns occur when Stalactites and Stalagmites meet as in the pic on the left. Cave paintings are those barely recognizable renderings of bison or mammoths of a quality often seen in elementary school rooms or modern art museums in New York. This is what Indians did for a living before they got into the casino thing. Indians were also the first spelunkers. Spelunkers are the idiots that explore caves for the fun of it.
