File:St Peters Mission - Near Cascade Montana - 1884.jpg
In 1884, the mission consisted of two log buildings -- a chapel with a bell tower connected to a common sleeping area for priests, and a lower structure which consisted of a sleeping area for nuns and a kitchen.
Depicted here are several of the Ursuline nuns with some Native American children/students. In the wagon at the right is Mary Fields, also known as "Stagecoach Mary", a former African American slave who came to the mission in 1885 to nurse one of the Ursulines. She stayed at the mission until 1894.
