Danger: Live military ammo washing up on Washington Coast

GRAYS HARBOR COUNTY, Wash. – Sheriff’s officials in Grays Harbor County are warning residents about multiple reports of live 20-mm high-explosive military anti-aircraft rounds washing up on the beach there.

“These rounds should be considered dangerous” and “can explode upon impact,” the sheriff’s office said in its warning issued Monday, adding in all caps: “*DON’T TOUCH * DON’T MOVE * DON’T TRANSPORT*.”

The live rounds, which are washing up in the North Beach area, are 6 to 8 inches in length and 20 millimeters in diameter. They resemble large rifle ammunition, said Chief Criminal Deputy Brad Johansson of the Grays Harbor County Sheriff’s Office.


Many of the rounds have been found encased in a black rock or sludge matter. They are believed to be from the World War II era, which makes their stability unknown.

No injuries have been reported so far in connection with the ammo.

Anyone who spots any of these rounds is urged to leave it in place, mark its location and contact the Grays Harbor County dispatch center at 360-533-8765.
