Park officials were alerted that a man had fallen from a rim trail east of Mather Point at about 4:20 p.m. Thursday, according to a park statement.
“Due to terrain, time of day and safety concern, recovery operations have suspended for the day and will resume in the morning,” the statement said.
The Grand Canyon Regional Communications Center received a report of a man who had fallen from the edge of the rim trail east of Mather Point.
The Man fell some 400ft as park visitors watched in horror.
Officials said 29-year-old Juan Carreras-Soto was visiting from Las Vegas when he fell over the edge of the rim trail east of Mather Point.
Responding units included park rangers, technical search and rescue team and the park helicopter.
A search over the edge was unable to locate the man, but authorities say the park helicopter was able to locate the body below the rim.
An investigation into the incident is being conducted by the National Park Service.
In March last year, John N. Anderson, 53, of Grapevine, Texas, died after falling off the rim near El Tovar Lodge while visiting the park with his family.
Just one month later, in April 2014, 45-year-old Jody McDaniel of Flagstaff, Arizona, fell off the South Rim at Mather Point, not far from Thursday’s deadly incident.
According to park statistics, there have been some 685 deaths recorded so far at the Grand Canyon.
Nearly 5 million people visit the Grand Canyon each year and an average of 12 people die there annually.
