Workers offload an Alaska Railroad train that delivered tons of snow to Anchorage, Alaska, on Thursday, March 3, 2016, after traveling 360 miles south from Fairbanks. The snow will be used to help provide a picturesque ground cover on the streets for the ceremonial start of the 1,000-mile Iditarod Trail Sled Dog Race in Anchorage, where persistent above-freezing temperatures have melted much of the local snow. The competitive part of the race kicks off Sunday 50 miles to the north in Willow. AP Photo/Rachel D'Oro
