Glencoe is a small town in South Australia, Australia located approximately 25 km west of Mount Gambier. In its heyday the township was divided into Glencoe and Glencoe West.
First established in 1844 by Edward and Robert Leake as a sheep station, the Leake brothers named the settlement after Glen Coe, Scotland where the infamous massacre took place in 1692. Originally from Tasmania, they brought with them the Saxon Merino sheep and in 1863 built the extensive Glencoe Woolshed, which still stands today as it was and now serves as a museum. The historic Glencoe Woolshed and Glencoe Station Stables and Coach House are listed on the South Australian Heritage Register.
A branch from the Mount Gambier railway line was built to Glencoe in 1904 to service the cheese factory. This branch closed in the 1950s when the main line was converted from narrow to broad gauge.
Lake Leake, an extinct volcanic crater associated with the Newer Volcanics Province, formed when rising red-hot molten rock encountered water in the limestone plain. Massive steam-driven explosions blew rock and lava high into the air. Powdered rock (ash)and rocks fell back to form a low rim around a wide flat crater - a part of which remains today. Lake Leake and the nearby Lake Edward, are unique in the Mount Burr Range. They perch above the regions water table and are filled by rainwater and run-off only. Pollen spores collected from lake sediment indicate that the volcanic activity occurred here much earlier than 20,000 years ago.
