mountain mass in northeastern Tasmania, Australia, comprising a plateau of 30 square miles (78 square km) made up of igneous rock. It mostly lies above 4,500 feet (1,400 m), making it the highest land in the state. The loftiest portion stretches 7 miles (11 km) from Legge Peak (Legges Tor; 5,161 feet 【1,573 m】) southeast to Stacks Bluff (5,010 feet 【1,527 m】). The surface is covered with many small hills and lakes. Ben Lomond lies within a 62-square-mile (161-square-kilometre) national park, the major winter-sports resort for northern Tasmania. Tin and wolfram (tungsten) have been mined on the southeastern slopes. It was named in 1804 by the administrator and explorer Lieutenant Colonel William Paterson for a mountain in Scotland.
