More than 85 firefighters, police officers and others participated in the North Dakota 9-11 Memorial Stair Climb – held at the state Capitol.

"The 9-11 stair climbs are nation-wide events, designed to commemorate the responders in New York City who climbed 110 stories of the World Trade Center," said Mandan firefighter Andrew Beck, one of the event's organizers. "It's a common thing for firefighters to climb stairs into a building where there is a problem and try to rescue people. And that's exactly what they did."

More than 100 firefighters from across North Dakota gathered in Bismarck today to climb the stairs of the State Capitol.

It’s to remember those who lost their lives in the 9-11 attacks in 2001.

The firefighters gathered at the Capitol steps for a short ceremony. They then went inside, and in groups of six climbed the inside steps.

“So the event will involve people starting at the steps, at the bottom,” said Mandan firefighter Andrew Beck. “They’ll walk up 17 floors, take the elevator down, and because we need to get to 110, they will do that six times.”
