Annular Eclipse
U.S. national parks are the place to be on May 20, 2012, to see the first solar eclipse in the United States in 18 years.
The eclipse begins over the Pacific Ocean and, from south of the Aleutian Islands, travels to the California coast at Redwoods National Park. From there, traveling at 1,000 mph, the shadow of the eclipse races south and east over 30 national parks in California, Nevada, Arizona, Utah, and New Mexico, and even into west Texas before sunset.
The grand show is a view of the moon centered on and covering more than 95 percent of the sun, and you'll see it—weather permitting—from the beach at Redwoods National Park, Lassen Volcanic National Park, Zion National Park, Bryce Canyon National Park, Glen Canyon National Recreation Area, Canyon de Chelly National Monument, and Petroglyph National Monument in Albuquerque.
Grand Canyon National Park, Navajo National Monument, Chaco Culture National Historical Park, and other parks of the Southwest will have other wonderful eclipse views. More than 125 national parks from western Oklahoma, Kansas, Nebraska, Minnesota, and the Dakotas, and even parks in Alaska, will have views of a partial eclipse.
This is a wonderful opportunity for park visitors. Several parks already have plans for eclipse programs in the days preceding the eclipse and on the day of the eclipse. At these parks, rangers will help visitors safely view the solar eclipse. In some parks, you'll be standing in the footsteps of ancient peoples who have marked these events for over 1,000 years.
