A 4-year-old girl on a vacation trip to the Grand Canyon has died after falling off the canyon edge.

National Parks Service spokeswoman Maureen Oltrogge says the girl fell near Mather Point just before noon and her father immediately scrambled down the cliffs to reach her.

He started CPR, and a Parks Service ranger who rappelled down the canyon also began trying to resuscitate the little girl, to no avail.

Oltrogge says the child's death is a tragic reminder to everyone that extreme care needs to be taken at the canyon rim, especially with children.

The little girl is from Arizona, but her name and hometown won't be released until Wednesday.
