{"id":2437,"slug":"ruby-falls-chattanooga-tennessee","story":[{"heading":null,"paragraphs":["Ruby Falls was found by accident, 260 feet inside a mountain, by a man digging for a different cave. Leo Lambert — an Indiana chemist and cave enthusiast who'd married his sweetheart Ruby Losey in 1916 — spent a decade scheming to reopen Lookout Mountain Cave, the cavern sealed when a railroad tunnel was cut through the mountain in 1905. In 1928 his company started drilling an elevator shaft: ninety-two days, five feet of limestone a day. At 260 feet a worker's jackhammer broke into a void and air rushed out.","Lambert crawled in with a small party and didn't come back for seventeen hours. What they found was a whole separate cave — underground streams, formations, and at its end a 145-foot waterfall plunging in the dark, fed by a source nobody has ever located. He named it for Ruby. The excavated limestone became the 'Cavern Castle' — a fifteenth-century-Irish-looking entrance building — and in 1929 the first commercial elevator in an American cave started carrying tourists down.","The original cave tours closed in 1935 — the falls outdrew everything — and the roadside signs made 'See Ruby Falls' a Southern institution. The falls still run in the dark 1,120 feet under the mountain's summit, their water source still unmapped, discovered only because a man digging to one cave broke into another.","Ruby Falls is the archive's accidental file — the 145-foot underground waterfall found when an elevator shaft hit a void at 260 feet, named for the discoverer's wife, still falling in the dark with its source unknown."]},{"heading":"Why this file matters","paragraphs":["Ruby Falls is the archive's void file — the waterfall Leo Lambert found in 1928 while drilling toward a different cave, 1,120 feet inside Lookout Mountain, where the water's source remains unknown and the elevator cab dates to 1929.","A falls found by accident keeps its shaft — the file's suggestion being that Ruby Falls' hold is the breakthrough: the jackhammer hitting the void at 260 feet, the air rushing out, the seventeen hours in the dark finding the waterfall he named Ruby."]}],"name":"Ruby Falls","aliases":[],"type":"CAVE","type_label":"Cave","cats":["LOCAL_FOLKLORE","HAUNTED_PLACE","NATURAL_WONDER"],"groups":["hauntings","legends","nature"],"desc":"The 145-foot underground waterfall inside Lookout Mountain.","full_desc":"A cave in Chattanooga, Tennessee, Ruby Falls is filed here for what the record attaches to it.
