A Yellowstone National Park employee is dead after she took a fatal tumble from a park cliff.
Early Friday morning, Estefania Liset Mosquera Alcivar, 21, a concessions employee from Ecuador, fell to her death from Grand View Point above the Grand Canyon of the Yellowstone River.
Her body was recovered just after 10 a.m. by park search and rescue crews in a helicopter.
According to a park release, Alcivar was socializing with a small group of coworkers near the trail along the rim when she fell over the edge of the canyon at approximately 3:15 a.m.
Her companions, who witnessed the fall, dialed 9-1-1 and park rangers and paramedics responded. Rescuers were able to locate her below the rim at first light and determine that the fall was not survivable.
According to the park's website, the canyon ranges from 800 to 1,200 feet deep.
The incident remains under investigation.
