Figure 1. Crater Lake in Oregon . . .Click to Enlarge Image

The year 2002 marks the 100th anniversary of Teddy Roosevelt’s establishment of Crater Lake National Park. Over that century, 25 million people have visited the United States’ deepest lake, but only recently have scientists studied its ecology extensively. Yet Crater Lake has been reluctant to reveal its mysteries. Years of research into and controversy about deterioration of the lake’s crystal-clear water were resolved only in the 1990s. The author, who has studied Crater Lake since 1967, takes readers on a combined ecological and historical tour of this spectacular resource.
