Friday will mark the 83rd anniversary of the discovery of Ruby Falls near Chattanooga, Tenn. The first 83 visitors Friday will get in for the original ticket price of only $2. Doors open at 8 a.m., so visitors are encouraged to arrive early to get the special discounted ticket, as well as a vintage postcard.

Ruby Falls was discovered by Leo Lambert on Dec. 30, 1928. Lambert, along with a small crew, came upon a number of unusual and beautiful rock formations, flowing passages and several stream beds. Pushing their way deeper and deeper into the cave, they finally reached its marvelous jewel, the waterfall.

The round trip journey took them about 17 hours. Lambert named the waterfall after his wife, Ruby.
