MAUCH CHUNK, a town in the state of Pennsylvania, North America, capital of Carbon county, is situated on a creek of the same name on the Lehigh River, 100 miles N.E. of Harrisburg. The surrounding country, though barren, is rich in coal and iron, which supplies Mauch Chunk with the most of its trade. The principal coal mines are about 9 miles W. of the town, and are reached by a railway. The original town is built in a narrow ravine near the river; but a new town is now rising on the top of the hill to the E. It contains a court-house, and other public buildings. Pop. (1850) 3500.
