A 21-year-old concession worker fell to her death early Friday in Yellowstone National Park, Reuters reports. Estefania Alcivar was hanging out with coworkers near the Grand Canyon of the Yellowstone River around 3:15 am when her coworkers say she fell into the canyon. According to the Casper Star-Tribune, Alcivar's coworkers called 911, but rescuers weren't able to recover her body until nearly seven hours later. The Grand Canyon of the Yellowstone River is 800 to 1,200 feet deep, NBC News reports.
Alcivar is from Ecuador. The National Park Service hires workers from abroad to give young people the opportunity to "come here to improve their English and learn about this country." Her death is under investigation. Earlier this summer, a man from Oregon died when he fell into a hot spring at Yellowstone. (More Yellowstone National Park stories.)
