Built in 1962. This cottage-style cabin was built to house the Osler fire-tower watchmen. The Osler fire tower was constructed following the cabin. This cabin was put on Birchcliffe Lake because it was the closest lake to the tower site that aircraft could land on it's surface. This cabin is almost identical to both the Big Crow Lake and White Trout Lake (still active) cabins. It has three rooms inside - two bedrooms and a main room.
