Jeffrey H Ryan is an author, adventurer, photographer, and historian. He has written several books about his outdoor exploits, his fascination with hiking trails, and a deep appreciation for history woven into walks across contemporary landscapes. His latest book, This Land Was Saved for You and Me, traces the path from Olmsted’s first wanderings in Yosemite to the signing of The Wilderness Act in 1964. In this episode of Nature Revisited, Jeffrey delves into the history of rescuing America's public lands, and both the notable and lesser-known people who gave their all to protect forests and wilderness areas before they would be gone forever and ensured that all Americans would retain the benefits of ownership.
