Beginning in 1964, the area was used as an outdoor classroom for local 5th & 6th grade students. A day spent in the “classroom” was coordinated by the public school teachers assisted by guest instructors from the Iowa Department of Natural Resources, the Natural Resources Conservation Service, and the Marshall County Conservation Board. Together they have helped the students understand their relationship to soil, air, water, sunlight and all living things. In 1992, Leonard and Mildred Grimes began donating parcels of 160 acres of land to the Iowa Natural Heritage Foundation. A reserve life-estate retains use of most of the land and farm income for as long as either of them lives.
