Loch Stack

Loch Stack is a large, irregularly shaped freshwater loch in the Northwest of Scotland. It lies approximately four miles (six kilometres) southeast of Laxford Bridge and is surrounded by mountains. Ben Stack rises steeply from the loch's southwestern shore and Arkle lies directly to the north. The outflow from Loch More, which is about 1 mile (1.5 kilometres) south of Loch Stack, is carried (via Loch nan Ealachan) by the small river An Earachd into Loch Stack.
