Frontiersmen used to call a passage through the mountains a "break". Such breaks were a rare thing indeed, offering the early settlers an opportunity to take their frontier lives to a new level. Layer upon layer of history welcomes today's visitor, as does the still resplendent beauty of this unique 4600-acre park. Established in 1954 by an act of Congress initiated by the efforts of the two states it crosses, Virginia and Kentucky, it is now one of only two such interstate parks in the USA.
