In September 1925, Mr. Thomas Jenkins, a carpenter of Llangorse, Breconshire, recovered a dug-out canoe of oak from Llangorse Lake. This lake is situated six miles to the east-ward of the county town. It is about 500 ft. above sea-level, in the valley and near the source of the stream known as Afon Llynfi, which flows northward (into the Wye) along the western escarpment of the Black Mountains. The lake is a mile in length and in greatest breadth, and is of glacial origin.
