"Dismayed that his son's adoptive home had no Catholic church, Frenchman Achille Wibaux instructed Pierre to build one here. The rancher contributed $2,000 for the construction of this wood frame, vernacular Gothic Revival structure. It was built in 1895 by R.R. Cummings and Eugene Blias of Glendive. The Wibaux congregation being at that time a mission of Miles City, Father Van der Broeck of Miles City superintended the church's construction. In 1938, the church was enlarged and its exterior walls covered with scoria, a lava rock common to the badlands of the area. Father Leahy, pastor of the church beginning in 1931, conceived the idea of a scoria facing, and volunteers from the congregation went rock picking in wagons and pickup trucks. Father Leahy recorded that "Patient men did a beautiful job of laying the rock up to and on the steeple." The building served as Wibaux's Catholic church until 1965, when a new church was built and this building was converted to a catechism school."
