On July 30th, 1921, the postal service expanded in the territory of Alaska with the assistance of dog teams. The department would also open weekly service, hauling through Ruby to Long Poorman, Ophir, McGrath, and Togotna. The mail hauled by dogsled to various destinations was generally limited to first class mail. Otherwise Alaskans served by dogsled had to wait for spring breakup for that mail to be hauled by steamship or wagon. Dogsled mail would stay in service in some areas of Alaska for decades and would only end in 1963, when the last U.S. Mail hauled by dogsled occurred between Gambell and Savoonga.
