Caprock Canyonlands: Journeys into the Heart of the Southern Plains, Twentieth Anniversary Edition (Environmental History Series)
"Caprock Canoynlands keeps its place on our bookshelves... for its exploration of a deeply human activity: the search for the beauty of the earth, the depth and strength of our ties to it, and the ways those appear in a particular landscape... here illuminated by love." - from the afterword by Thomas R. Dunlap"
