A fleet of snow sweepers return to the 773d Civil Engineer Squadron’s Snow Barn after clearing an early-season snowfall from the flight line on Joint Base Elmendorf-Richardson, Alaska, Sept. 24, 2021. Snow removal is one of the most challenging and important duties handled by the squadron, as much of the installation’s mission revolves around their ability to quickly clear roads and runways.
