An eight-year-old girl was killed while hiking a Yellowstone National Park trail in Wyoming on Sunday morning. The victim, identified by park officials as Zahra Allahyari of Poway, California, reportedly died after falling more than 500-feet into the Grand Canyon of the Yellowstone River.

Zahra and her family had been touring the park’s Brink of the Lower Falls trail Sunday when she reportedly stepped off the trail, losing her footing two-thirds of the way down the trail, the U.S. National Park Service confirmed. Officials estimate Zahra fell approximately 550-feet into the canyon. Her body was retrieved by park officials Sunday afternoon.

The fatality marks the third accidental death at Yellowstone National Park this year. Darien Latty, 22, of Demorest, Georgia, was found dead Saturday after being swept downstream while tubing with friends on the Lamar River. An unidentified 36-year-old Taiwanese man lost his life hiking Fairy Falls trail on June 9 after being hit by a falling lodgepole pine tree.
