The Grand Canyon, Wupatki National Monument and Sunset Crater Volcano are some of the geologic and cultural gems of the National Park Service. This summer, KNAU's Earth Notes series will highlight these, and other special places across the Southwest in honor of the Park Service's 100th anniversary. In the sixth and final installment of the series, we profile photographer George Grant, the first chief NPS photographer. For 25 years, he took iconic shots of the Grand Canyon and other parks of the Southwest.
