The shuttle is not a park convenience. It is what the 1978 storm left you.

You come to the Outer Cape for this beach — Coast Guard Beach, Eastham, the Nauset shore of Cape Cod National Seashore, not the other Coast Guard Beach in Truro. You come for the start of what Thoreau called the Great Beach, a name the Park Service still keeps, and you expect to leave the car on the sand.

You do not. On this shore you do not park at the beach because the ocean took the lot.

People still walk up to the white station at the end of Doane Road as if it were the public face of the place. It is a life-saving building. It is not a visitor center. NEED, the park’s residential environmental-education facility, lives in it. The building is not open to the public. Walk the grounds. Look at the ocean. Look the other way, at Nauset Marsh — tidal flats, shorebirds, the bike-trail bridge — and at Nauset Spit running south, a living barrier. The grounds are what you get.

This station is here because the backside wrecked ships. More than three thousand wrecks are attributed to this shore since the Sparrowhawk in 1626. One of the original nine Cape Cod Life-Saving stations went up at Nauset after the 1871–72 federal reorganization. The first building stood about 350 yards southeast of this one; erosion forced a replacement. This station was built in 1935 and 1936, manned January 9, 1937, and kept as a Coast Guard station until 1958. The NPS historic-structure study has the crew departing September 15, 1958. The U.S. Life-Saving Service Heritage Association dates the close to September 16, 1958. In 1961 the first headquarters of Cape Cod National Seashore opened in this building.

Henry Beston designed a cottage on Nauset Spit in 1925 — the Fo’c’sle, twenty-one feet by sixteen — and wrote The Outermost House from it in 1928. He gave the cottage to Massachusetts Audubon in 1959. The sea took it in the February 1978 northeaster. That is the shore’s book. The spit is where the house stood. You will not find it.

The Park Service’s own storm page is the Tuesday morning. Winds peaked at 92 miles an hour at Chatham about six in the evening on Monday. After midnight a new-moon high tide ran about 14.5 feet above mean low water. On Tuesday the eye passed, the sky went blue, and more than a hundred people stood in front of the old station and watched storm waves “virtually obliterate the parking lot and changing room complex.” Waves swept most of Nauset Spit. Four houses went, including the Outermost House. Wind-built dunes were cut down to low mounds.

The official geology sits beside that telling. They are the same event. NPS calls the overwash the way a spit retreats with a retreating coast, turning over on itself and keeping the marsh behind it. The shore’s sentence is simpler: 1978 took the lot and the house.

In the 1980s the Park Service built a new lot well away from the beach, “to allow the natural give-and-take processes of erosion to continue.” That lot is Little Creek, inland, about a mile and a half east of Salt Pond Visitor Center at 50 Nauset Road, by way of Nauset and Doane. In season you do not park at the station unless you are an Eastham resident or you carry a handicap placard. The shuttle runs from Little Creek.

This is not a town swimming beach. If you learned Cape Cod on the bay — warm water, small chop, a town sticker — you have cold water and real surf here, a spit the federal landscape is allowed to let move. Seals haul out on the sandbars in summer, gray, and at the spit in winter, mostly harbor. The park asks a hundred and fifty feet.

Walk the grounds. Look at the marsh. Walk the spit if the tide will have you. You came for the beach. What you find is a decision the storm already made. The lot the storm took is gone. The shuttle is what 1978 left in its place.
