Cape Shoalwater was never stable ground, though no one knew that when the United States established a military reservation there in 1854 after negotiating with Chief Ma-Tote of the Shoalwater Bay Tribe. The government built the Willapa Bay Light on the cape in 1858, one of the earliest lighthouses in Washington Territory, because the waters around the cape were treacherous and ships kept wrecking. Even with the light, navigation remained dangerous, so a lifesaving station went up in 1878. Captain George Johnson was assigned to the station, and he left his land claim near what is now Raymond to buy property on the cape. When his wife Lucy platted North Cove on that property six years later, she was building a town on shifting sand - a fact that geology would make painfully clear over the coming decades.

The erosion started slowly, then accelerated. By 1920, the Coast Guard was already moving equipment from the military reservation to Tokeland because the ground at North Cove was disappearing. The Willapa Bay Light, the lighthouse that had guided ships since 1858, toppled into the ocean in 1940. By 1950, the entire lifesaving station was in danger, and the facility was relocated to Tokeland - buildings salvaged when possible, otherwise abandoned to the waves. The causes run deeper than simple surf. When dams went up on the Columbia River beginning in 1933, they trapped the sediment that had once flowed downstream and replenished the coastal sand supply. The sand spit protecting North Cove began to thin. As the channel shifted northward, storm waves broke closer to shore, biting into bluffs and dunes with increasing ferocity. By 2016, the ocean had consumed 60 residential properties and 537 land parcels. North Cove earned a new name: Washaway Beach. At 50 to 100 feet of shoreline lost per year, it became the fastest-eroding point on the entire West Coast.

What makes North Cove remarkable is not just the erosion but the fact that people still live there. Homes perch near crumbling bluffs. Garages have slid into the surf. Portions of State Route 105, the only road connecting communities along the north shore of Willapa Bay, have been rerouted multiple times as the pavement drops away. Residents describe watching their yards shrink season by season, measuring the distance between their foundations and the cliff edge the way farmers watch a drought. Some have moved. Others refuse, either because they cannot afford to or because this is home and home does not move just because the ground does. The nearby Shoalwater Bay Indian Reservation faces the same threat, its land eroding into the bay from a different angle. For the Shoalwater Bay Tribe, the erosion is not just a property problem - it threatens the land base of a people who negotiated for this ground when the reservation system was new.

In 2016, a lifelong North Cove resident tried something simple. He spent $400 on a truckload of basalt cobble - fist-sized rocks - and dumped them on the beach. The idea was counterintuitive: instead of building a rigid seawall that the ocean would eventually undermine, use loose natural materials that absorb and dissipate wave energy the way a natural beach does. He and his partner watched as erosion seemed to slow at the site. The approach, called dynamic revetment, caught the attention of researchers at the Washington Department of Ecology. Studies confirmed that the cobble, combined with driftwood and dune vegetation, was creating a more resilient shoreline that flexed with the waves rather than fighting them. The success drew national attention and federal investment. In 2025, the National Oceanic and Atmospheric Administration awarded a $13 million grant to stabilize the area and protect State Route 105 from further erosion. A town that the ocean seemed determined to erase found an unexpected answer: work with the water instead of against it. North Cove is still eroding, but for the first time in a century, there is reason to believe it might not disappear entirely.
