Midwest Region of the National Parks Service donated these videos to The Ohio State University to lead to the enhancement of our nation's natural resources and preserve these videos for future use. The recordings are of fly-overs of 8 rivers in Ohio-- the Chagrin River, the Stillwater River, the Little Muskingum River, and the Big Darby Creek, Sandusky River, White Oak Creek, Four Mile Creek, and St Marys River. These videos were made in the 1970s.
