Tuesday will mark the 11th anniversary of the Sept. 11 terror attacks, in which hijackers seized control of four airliners and rammed them into the World Trade Center in New York City, the Pentagon in Arlington, Va., and the countryside near Shanksville, Pa.

Local groups have made it their mission for Juneau to remember 9/11 and its victims.

A commemoration ceremony is being held at Riverside Rotary Park Tuesday morning. The event, hosted by the Glacier Valley Rotary Club, has become a somber yearly tradition in Juneau.

“It’s an opportunity to recognize our first responders and honor our promise to never forget the tragic 9/11 attacks that took so many lives and sent shock waves around the free world,” said the club’s President Richard Burns in a written statement.

That event starts at 9:40 a.m. and ends at 10:15 a.m.

Civic-minded Juneauites can also participate in a volunteer opportunity to mark the occasion.

SAGA is holding events from 9 a.m. until 4 p.m. in Juneau, Haines and Skagway.

In Juneau, SAGA is teaming up with the Southeast Alaska Master Gardeners and the Forest Reclamation Team, according to Scott Young, SAGA’s director of programs.

“We will be doing garden work and cleanup around the Pioneer Home,” Young said. SAGA will provide tools, he said, and he added, “We do have some ability to give a person a ride to that event, if they need it.”

In Haines, SAGA and the American Legion will be working on the Fort William H. Seward parade ground.

“They’re going to be doing some building maintenance, repair and some general cleanup,” Young said.

Skagway volunteers will be pulling weeds with the National Park Service and the Taiya Inlet Watershed Council, said Young.

“We’re doing this on 9/11 because we want to recall and make people remember the terrible events of the day,” Young explained. Part of the message he said he hopes the events send is that “we’re here, we’re well, we take care of each other.”
