A twelve-page report authored by John B. Yeon, chairman of the Pacific Northwest Regional Planning Commission's Columbia Gorge Committee, written to Mr. Lawrence Merriam, regional officer for the National Park Service's State Park Division, on the subject of a proposed interstate park in the Columbia River Gorge along both sides of the Columbia River. In the report, Yeon requests the support of the National Park Service in purchasing non-agricultural land to establish the park. Yeon describes five specific areas in the Gorge where the proposed land would be purchased: Cape Horn, Beacon Rock, White Salmon, Latourell, and Crown Point.
