Several Treasure Valley fire departments are participating in the March event in Seattle.
Firefighters wear full gear and climb the Columbia Center's 69 floors.
It's a grueling test of physical and mental agility.
So far, the Boise Fire Department is in the fundraising lead, with more than 35-thousand dollars.
You can donate in a specific firefighter or department name.
