In less ancient times this isthmus became known as the Gap of Danger where the plainsmen met the less sophisticated, but often more stubborn stock of Joyce and Flaherty country. Here was the stage where conflicting civilisations rubbed shoulders, and often swords.
Today the district of Clonbur is endowed with natures choicest gifts mountains, lakes, streams and woodlands. Mount Gable offers the visitor who likes an easy climb a panoramic view of breath-taking beauty. The lakes need no introduction to discerning anglers from these islands and the continent. At present, with the co-operation of the Forestry Division of the Department of Lands, forest walks of scenic interest are being developed. Here one can rest, stroll or picnic in a friendly and picturesque environment or visit the ruins on the Petersburg Estate, seat of the Lynch family, one of whose members John Lynch was a signatory of the American Declaration of Independence.
