One room school
While driving around looking for birds I came across this old building located on Lower Brule off reservation trust land. I believe it was a one room school. In the photo below, you can see the frame of a chalk board through the door. Based on the plaster and lath, the space for the stove and the light fixtures (zoom in). I'm guessing this was built in the 30's or earlier. You can see more photos of the school house in this photo album .
