DENVER – Thousands of people climbed up and down the steps at Red Rocks Amphitheatre Monday to pay respects to the first responders who lost their lives in the terror attacks of Sept. 11, 2001.
Men, women, children and firefighters in full gear took part in the annual event, which is the largest in the country.
Participants took nine laps around the amphitheatre, which is approximately equivalent to climbing the 110 stories at the fallen World Trade Center towers in New York City. Monday marks 16 years since the attacks, which killed thousands.

The $35 registration fee for the stair climb benefits the FDNY Counseling Services Unit and also supports the families of those who died on Sept. 11.
The event was one of several stair-climb events held throughout the region Monday. Firefighters also scaled stairs at Good Samaritan Medical Center in Lafayette and at the Transamerica building at 18th and California streets in downtown Denver.
