One of about 25 cabins at an abandoned church camp near Cherry Tree, PA. There is also a large rugged auditorium with a sloping floor and benches as pews. Barn doors lined both sides. When open, I suppose the structure would be like a pavilion. There is also a dining hall, a small social area with booths and tables, and a motel of sorts that made me think of Nabokov.
The town now called Cherry Tree had a cheery tree that marked the eastern boundary of a Penn family purchase from the Six Nations of the Iroquois in 1769.
The tree then became the intersection of Clearfield, Cambria, and Indiana counties.
