The Bluff That Keeps Losing: Erosion, a Writer's Cottage, and a Condemned House
Coast Guard Beach is not a stable place. It sits below a glacial bluff on the outer edge of Cape Cod, fronted by the Nauset Spit barrier-beach system, and the erosion that shapes it has already taken one literary landmark and, in 2024, one Park Service-owned home. The same forces that make this stretch of Atlantic coastline dramatic to look at are the forces actively eating the ground under it.
A Cottage Built to Watch the Coast
In June 1925, the naturalist and writer Henry Beston built a small dune cottage about two miles south of what is now the Coast Guard Beach parking area. It was a modest structure — two rooms, twenty feet by sixteen, with ten windows, a wood stove, two oil lamps, and a hand pump reaching a well beneath the floor. He called it the Fo'castle.
Beston moved in for real in September 1926, intending a two-week stay. He stayed a full year, leaving in September 1927, with the Atlantic at his front door and Nauset Marsh at his back. What came out of that year was The Outermost House, a close, patient account of the dunes, the birds, the tides, and the isolation of living on an exposed barrier coast. The manuscript was finished by April 1928 and published that October.
The book did more than describe the place — it helped define how the place would later be protected. When the National Park Service evaluated this stretch of Cape Cod for national-park status in the 1950s, Beston's book was part of the record it consulted. In 1964, the cottage site was dedicated a National Literary Landmark, and Massachusetts Governor Endicott Peabody told the crowd gathered for the ceremony that the book was one of the reasons Cape Cod National Seashore existed at all. Cape Cod National Seashore itself had been established a few years earlier, in 1961, when President Kennedy signed the bill creating a 43,607-acre park — the first national park assembled primarily from private land. Beston had already given the cottage property to the Massachusetts Audubon Society in 1959, before any of that recognition arrived.
The Storm That Took It
None of that history saved the physical cottage. During the Blizzard of 1978, in February, high tides swept over the barrier beach and carried the Fo'castle into the sea. Its original site is now underwater — not eroded gradually into memory, but taken outright by one storm.
That same blizzard hit the wider beach hard. Winds peaked at 92 miles per hour in nearby Chatham. The tide ran 14.5 feet above mean low water. Four houses were destroyed. Coast Guard Beach's parking lot and changing facilities were obliterated, and its dunes were reduced to low mounds. It is one of the clearest single-event demonstrations on this coastline of what an outer Cape storm can do in a matter of hours.
The National Park Service's response, worked out over the following years, was not to rebuild the infrastructure back where it had been. In the 1980s, the Park Service moved the Coast Guard Beach parking lot away from the immediate beachfront specifically to let natural erosion and overwash processes continue, rather than trying to hold a fixed line against them with engineering. That decision reflects a broader position: on a barrier coast like this one, a beach that is allowed to move is more durable, in the long run, than a beach that is fought to a standstill.
A House Condemned in 2024, Demolished in 2026
The same dynamic that took Beston's cottage in 1978 is still active on the bluff above the beach today, and it is not moving on a geological timescale — it is moving on the timescale of a news cycle. The Bartlett House, a 1960 cottage on the eroding bluff near the Coast Guard station that the National Park Service had owned since 1964 and used as seasonal staff housing, had its front-yard setback from the bluff edge measured at roughly 45 feet in April 2023. By mid-2024, that setback had collapsed to under 13 feet. In the fall of 2023, saltwater infiltrated the house's fresh-water well, making the site functionally unlivable before any demolition order existed.
On July 9, 2024, the Department of Housing and Urban Development determined the Bartlett House was unsuitable for continued habitation. Under the process that followed, if the house went unclaimed by a government or homeless-service agency after a 20-day appeal window, the Park Service planned to demolish it before the sea did — and did so, beginning February 3, 2026. The bluff that gave Coast Guard Beach its station, its views, and its literary history is the same bluff working, in real time, to reclaim the ground underneath whatever is built on it.
What This Means for a Visit
None of this erosion history is hidden from visitors, exactly, but it also isn't obvious from a normal beach day. The 1936 Coast Guard station on the bluff, now the National Seashore's residential environmental-education center, sits close enough to both the Fo'castle's former site and the Bartlett House to make the pattern visible if you know to look for it: this is a coastline where the Park Service has deliberately chosen to let the shoreline move rather than defend it structure by structure. The parking lot was relocated once, in the 1980s, for exactly this reason.
The dunes above the beach still support the same kind of plant community Beston would have recognized — hardy, salt-tolerant species that colonize and stabilize shifting sand rather than trying to hold it in a fixed shape. Grey seals haul out along this stretch of coast, part of an ecological recovery that has, in turn, drawn white sharks that remain active well into the fall, after the lifeguard season ends. The National Seashore asks visitors to keep at least 150 feet from any hauled-out seal and to respect seasonal pedestrian and pet restrictions protecting nesting plovers and terns.
Coast Guard Beach rewards a visitor who understands it as a process rather than a fixed scene. The station on the bluff, the cottage that is no longer there, and the house that was condemned in 2024 and demolished in 2026 are three data points on the same line: a barrier coast that has been actively rearranging itself for at least a century, and that the National Park Service has decided, deliberately, not to stop.
