Jenolan Caves, a series of vast limestone caverns, situated on the west side of the Blue Mountains, in New South Wales, 160 miles W. of Sydney. They were discovered in 1841, and were set apart in 1866 as public property by the colonial government. In grandeur, magnitude, and rich variety they rival the Mammoth Caves of
Kentucky. See S. Cook's Jenolan Caves (Lond. 1889).
