Community groups Malama Makua and Hui Malama will hold a makahiki observance on Dec. 14 and 15, the service said.

Due to safety concerns, the reservation had been closed to all but essential security and demolition personnel since the first discovery of the munitions on Nov. 1.

The Army said it was forced to cancel the opening of the Makahiki, a traditional Hawaiian religious and holiday season, planned for Nov. 16 and 17.

Community members accused the Army of foot-dragging in providing the cultural access that is required under the terms of a 2001 court settlement with Malama Makua.

Following the detonation Monday of a 250-pound World War II bomb and a 81mm mortar and 106mm anti-tank round, a two-day range clean-up has been completed that removed any shrapnel and other debris, the Army said.

Thousands of sandbags were filled by soldiers to provide a protective barrier for the detonations, and to protect a petroglyph in the area.

"We express our sincere appreciation to the state of Hawai'i and those federal agencies who helped us get the necessary permits and approvals to remove these munitions as quickly as possible," said Col. Matthew Margotta, commander, U.S. Army Garrison Hawai'i. "I want to thank the soldiers who worked over their Thanksgiving weekend filling sandbags and building barriers."

Coordination of the actual detonations was a combined effort of the state's Department of Land and Natural Resources, Hawai'i Civil Defense, the Honolulu Police Department and Army personnel.

"To ensure public safety, we had to close Farrington Highway and clear the adjacent beach for two hours," Margotta said. "We appreciate the understanding and patience of the local communities as we conducted this operation."
