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.
