Linda’s Monthly Monday Morning Moaning’s for April 1st, 2024
On an April Fools Day, 78 years ago on Unimak Island, in the Aleutian Islands in Alaska the unthinkable would happen. At 1:30 am a 7.4-magnitude earthquake struck the North Pacific, at a location roughly 13,000 feet below the surface of the ocean. The earthquake created a tsunami that quickly traveled north to the Aleutian Islands and then south, where, five hours later, it would hit Hawaii. The Scotch Cap Lighthouse were a series of lighthouses on the southwest corner of Unimak Island.

The original lighthouse built in 1903 was a 45-foot wood tower on an octagonal wooden building. The light and it’s keepers would see many ship wrecks over the next few years, as in 1909 when a supply ship and it’s 194 crew members were guests of the light station for two weeks after the their ship the Columbia was wrecked. It would be two weeks before they could be removed from the station. The 1903 original Scotch Cap light, seen below, would be replaced in 1940, by a concrete reinforced lighthouse and fog signal building, built next to this original light.

On that April Fool’s Day in 1946, the nervous watch keeper noted the event of the trembling, in the log book, and that it ‘lasted but a minute’. Keeping in contact with the watch man at the light at the foot of the headland, by radio telephone. But 70 miles out in the Pacific a massive segment of the wall of the Aleutian Trench collapsed and fell to the sea bottom, 20,000 feet below the surface. This would create a series of seismic waves or known as a tsunamis, racing across the Pacific.
Within minutes a second tremor, shorter but much sharper rocked the Scotch Cap light, and again no damage occurred. Twenty minutes later the first tsunami approached Scotch Cap. As the wave moved into shallow water near the shore, it formed into a near vertical wall of water estimated to be roughly 100 feet high. Millions of tons of water exploded as the water engulfed the headland, destroying everything in its path. The off watch crew station rushed out of their quarters, were they were ordered to get to higher ground, knowing there would be further waves coming in. As they rushed to leave the building, one looked toward the sea and cried out, “the light, the Scotch Cap Light! It’s gone out.”
Not only had the light gone out but the fog signal and radio beacon were quiet. All attempts to raise the station by radio failed. The commanding officer high on the cliffs looked over the edge and found nothing but blackness. When daylight appeared the Coast Guardsmen made their way to the cliff edge and peered down. All that they saw that morning was the concrete platform and some broken pieces of concrete, all that remained of the Scotch Cap Light Station.

That morning the teletype machines sent out a message: “TIDAL WAVE PRECEDED BY EARTHQUAKE COMPLETELY DESTROYED SCOTCH CAP LIGHT STATION WITH LOSS OF ALL HANDS STOP TOP OF WAVE STRUCK THIS UNIT CAUSING EXTENSIVE DAMAGE BUT WITH NO LOSS OF LIFE STOP ENGINE ROOM FLOODED BUT EXPECT TO MAINTAIN EMERGENCY POWER IF NO FURTHER DAMAGE IS EXPERIENCED STOP WILL SEARCH FOR BODIES OF SCOTCH CAP PERSONNEL AS SOON AS POSSIBLE STOP REQUEST INSTRUCTIONS STOP”
The search for the five Coast Guard keepers found nothing, everything was gone. The five men would be found when the sea gave up their bodies five days later. The five men, Jack Colvin, Dewey Dykstra, Antony Pettit, Leonard Pickering and Paul Ness were identified only by dental records.

Ghost stories are not unknown around lighthouses, and after the April Fool’s Day disaster Scotch Cap joined the ranks of the haunted lighthouses. One night, both the generators broke down. Without power, there was no light and the foghorn was silent. A ‘Notice to Mariners’ went out on Coast Guard radio alerting the ships and aircraft. A Coast Guard cutter cruising within sight of Scotch Cap, raised the station asking why had the station sent out the warning? The cutter reported the the light was in view and burning brightly. The people who knew Scotch Cap, those of the old timers, just exchanged knowing glances.
All postcards used are from the authors collection, with the exception of the last image showing the concrete and wooden lighthouses, were I give my great appreciation to the ‘Keepers Log’ Winter 1986 for their excellent information and account on the disaster that struck the Scotch Cap in 1946.
