Big Moose Lake
Big Moose Lake, at the head of the Moose River, is a large lake about five miles (8 km) north of Fourth Lake in the Adirondacks in upstate New York. It is a popular spot amongst tourists all year round: boating, water skiing and hiking in the summer; cross-country skiing and snowmobiling in the winter.

The lake's popularity derives from its remoteness, climate and beauty, as well as its notoriety as the location of the murder of Grace Brown in 1906. Alleged ghost sightings and subsequent media attention have added to the allure.
