Sister Paula Mary Turnbull, of the Convent of the Holy Names in Spokane, is a prolific sculptor whose work includes the garbage-eating goat in Riverfront Park and adorns Spokane Community College, the city’s wastewater treatment plant, Central Valley High School, the Hillyard pool, Indian Trail Park and numerous other places. In 1972, Turnbull was named to the Expo Visual Arts Advisory Committee, which led the effort to bring sculptures to the fair. Art from Expo ’74 gained attention last week when the Spokane Park Board voted to remove an Expo-era sculpture by Charles W. Smith from its collection.
