A fourth-grade class from the Grand Canyon School will lead a Happy Birthday sing-along. Sunni Dooley will tell Navajo winter stories later in the day.
Before Grand Canyon became a national park, the land was home to and visited frequently by Native American tribes.
The park was protected as a game reserve and national monument before being designated a national park on Feb. 26, 1919. Now, more than 6 million visitors a year peer deep into the gorge, navigate river rapids, hike trails and camp under the stars.
