Ozark National Scenic Riverways will host special programs and school reunion activities at the historic Button Rock School and historic Cortoreva School site 11 a.m. to 3 p.m. Sept. 21.

Park rangers will be on hand to share a history of one-room schools in Shannon County. Former students and teachers invite the public to join in these events, which will include potluck lunches at both sites beginning at noon for all that would like to bring a dish to share. Visitors are encouraged to bring old pictures, a covered dish or sack lunch, and folding chairs.
