The twisted steel that sits outside Fort Carson’s main gate once sat in the dust-strewn rubble of the World Trade Towers in New York.

Eleven years later, that steel will set the stage for a ceremony remembering the deadliest attack on United States soil.

Fort Carson officials plan to hold a remembrance ceremony on Tuesday at the World Trade Center Memorial at Kit Carson Park to remember the lives lost on Sept. 11, 2001 and the soldiers killed in the two ensuing wars.

The ceremony is one of a few across military installations in Colorado Springs, though the only one open to the public.

Another steel beam from the World Trade Center will be dedicated at Schriever Air Force Base on Tuesday, while officials at the Cheyenne Mountain Air Force Station plan to hold a rememberance ceremony at the steel beam outside their complex.

Both of those events are closed to the public, because they will take place inside each installation’s secure perimeter.

At Kit Carson Park, Dave Roever — a Vietnam veteran badly burned in the war — will deliver a speech at the memorial. Roever is a public speaker who also co-founded Eagles Summit Ranch near Westcliffe.

The ranch helps wounded soldiers deal with the emotional strains of being wounded in combat, according to Roever’s website.

The ceremony at Fort Carson will begin at 10 a.m.
