				Mosquera Alcivar, a concession employee, was with a small group 
				of coworkers at the rim of the Grand Canyon of Yellowstone 
				shortly after 3:15 a.m. when she fell, according to accounts by 
				her companions, the park's public affairs office said in a 
				statement.
 Her body was recovered about four hours later and the incident 
				remains under investigation, the officials said. Alvicar is from 
				Quito, Ecuador.
 
 The incident along with three major wildfires burning in 
				Yellowstone come at the height of the summer tourist season and 
				as officials in both parks prepare for celebrations set for 
				Thursday marking the 100th anniversary of the creation of the 
				National Park Service.
 
 The fires have prompted authorities to close the south entrance 
				to the park, which last month saw an average of more than 2,400 
				vehicles per day.
 
 Yellowstone, which occupies the northwestern corner of Wyoming 
				and spills over into Idaho and Montana, was the first national 
				park established in the United States and remains one of its 
				most popular.
