Outer Island is part of the Apostle Islands archipelago in Lake Superior, and is called Outer Island for a reason. It's the farthest out from mainland Wisconsin and can be the hardest to get to. Nonetheless, once the timber on the mainland had been cut over, the lumber industry managed to get to the island multiple times, with the final major logging activity taking place in the 1950s, which is when most of these photos were taken.
The photos show the logging activities done by Ed Bush, a contractor from Ladysmith, Wisconsin, and his crew. They harvested hardwoods like birch for use by the Lullabye Furniture Company of Stevens Point, Wisconsin. Lullabye specialized in manufacturing cribs and other furniture for infants and children, hence the name. The remains of the camp are known today as Lullabye Logging. When the logging operation ended, a lot of equipment was simply abandoned in place -- it wasn't viewed as being worth hauling back to the mainland.
Equipment was hauled to the island with a World War II surplus landing craft, The Outer Island (originally LCT(5)-103), owned by the Lullabye Furniture Company. Logs left the island via that same landing craft. Because getting to the island by boat wasn't always possible, particularly in the winter when Chequamegon Bay froze over, Lullabye decided to construct an airport.

One of my assignments when I worked at Apostle Islands was to assess the condition of the surviving structures associated with Lullabye logging. The camp was easy. There's a clear, well-maintained trail to it from the light station. Assessment was easy, too. "Ruin" is nice short word.
The air strip was a different matter. It's still visible from the air--it takes a long time for an opening that big to revegetate to the point of blending in seamlessly with surrounding forest--but finding it on the ground involved some bushwhacking. But find it we eventually did, and discovered the hanger slowly mouldering into the soil.
We also found an old-fashioned sickle bar riding mower, an artifact that's destined to totally baffle any future hiker who stumbles across it sitting in the middle of an officially designated wilderness area.
