In the 1930s, the Civilian Conservation Corps built a two-story cabin, now known as the Olallie Lake Guard Station Cabin, at the south end of the Mount Hood National Forest for local forest rangers. With a rustic architectural style, it exemplifies buildings from the Depression period. In 1991, the building was added to the National Register of Historic Places. It now operates as a cabin for visitors, with a kitchen, living room, bunk bedroom, and loft for up to eight guests. Its lighting and refrigerator are fueled with propane, and it also has a stove, oven, water tank, and vault toilet. Located at an elevation of about , it can be reached by motorized vehicles, though snow may impede access to the cabin.
