'Pivotal moment' for the Manfred House

Author Frederick Manfred used a rock cliff for the back wall of the house.
Author Frederick Manfred used a natural Sioux quartzite rock cliff for the back wall of the house he built in about 1960 near Luverne in southwest Minnesota. Currently it serves as the interpretive center at Blue Mounds State Park but it has been closed since 2015 because water seepage from the cliff and other issues caused structural problems including rotting ceiling beams.
