Education
Beulah's educational system started with a one-room school house, located in an unused barn south of town. At its advent, only five local children attended the school. As its reputation grew, children from surrounding communities increased the school's attendance to over one hundred students. The school went on to receive several awards for educational excellence and was considered the pride of the town until a fire in 1934 destroyed the building. Beulah has an elementary, middle, and high school. The sports teams are called the Miners. The American Legion baseball team is called the Cyclones.
