Some of the other firefighting equipment founded in Chicago is less high-tech: the snorkel truck, the fire plug or hydrant, the collapsible fire escape and the fire pole, which was invented by a Chicago fire captain in 1874 so firefighters could slide quickly to the ground floor.
Lisa Clarke Devore, who was headed back to Denver from the resort, told The Associated Press she saw a fire truck and ambulance on the pass, as well two search dogs headed into the area of the slide.
