DLNR closed Hapuna Beach State Park Friday after a diver found an ordnance in waters offshore.
The diver brought the object ashore to the park concession area.
Hawaii County Fire Department and Police Departments were notified and DLNR Division of Conservation and Resources Enforcement (DOCARE) contacted the U.S. Army Schofield Barracks unexploded ordnance unit.
A team of experts arrived on the Big Island to determine what further action will be taken.
Meanwhile the public was evacuated by County Police and DOCARE and a safety perimeter established around the concession area where the object remains at this time.
The ordnance was taken to the Pohakuloa Training area where it will be disposed.
The park opens at 7 a.m. Saturday.
Thousands gathered at the memorial to pay tribute to those who paid the ultimate sacrifice and to those who survived.
You may remember the story we did earlier this week about the Pearl Harbor survivor who was headed here from the mainland for the ceremony, he was bumped from the flight and didn't know if he would get here in time.
It may take drivers a little longer to get around this weekend. On Sunday, there will be lane and road closures for the Honolulu Marathon.
