The closing of the camp was famously memorialized in Robert Lowell's Notebook 1967-68. Harriet Lowell's parents, the poet Robert Lowell and critic Elizabeth Hardwick, had a summer home in Castine. She was a camper at AIC in its last two seasons.

End of Camp Alamoosook

Less than a score, the dregs of the last day,
counselors and campers, man the last arc of the island;
the unexpected, the exotic, the early
morning sunlight is more like a premature twilight;
last day of the day, foreclosure of the camp.
Glare on the squatting tan, fire of fool's-gold °©
like bits of colored glass, it cannot burn.
The Acadians must have gathered in such arcs;
my cousin herded them from Nova Scotia °©
no malice, merely working his line of work,
herding guerillas in some Morality.
Old Order! The campers harden in their shyness,
then gruff, faint voices hardly say hello,
crying, "Do we love it? We love it."
