Sisters Joletta and Theodora Bird Bear live across from one another on a remote stretch of western North Dakota highway roughly 9 miles east of Mandaree, a town of about 600 people on the Fort Berthold Indian Reservation. Their homes are just past a cluster of four roadside oil wells and before the recently paved intersection on the other side of the hill. “Don’t look at Google,” says Joletta when offering directions to her home. “You’ll end up somewhere 30 miles away.” Joletta and Theodora, Mandan Hidatsa members of the Three Affiliated Tribes, have spent most of their lives on rural Fort Berthold without street addresses that allow for easy mail delivery, nor mailboxes at the end of their long driveways.To pick up her mail, Joletta drives to the Mandaree post office, where for more than 20 years her mother worked as the town postmaster. When she retired, Joletta succeeded her. All told, the Bird Bears staffed the Mandaree post office — a place of unique importance on North Dakota’s tribal lands — for more than 40 years.
