A 70-year-old old woman fell to her death in Grand Canyon National Park on Tuesday, the latest in a spate of fatalities in and around one of the most popular tourist destinations in the United States.

The woman, whom authorities have not yet identified, fell about 200 feet, according to Grand Canyon officials. She had been walking along the South Rim, about a mile east of Mather Point, when she veered several hundred feet off a trail, reported the Associated Press.

Around 1 p.m., park rangers received a distress call that someone needed help.

“She fell before we could undertake a rescue,” Grand Canyon spokesman John Quinley told the AP.

Park officials used a helicopter to retrieve the woman’s body. They were waiting to release the woman’s name until her family had been notified.

Her death is the fourth in and near the park since March 26, when the body of a Japanese tourist was found south of Grand Canyon Village. Two days later, on March 28, a Chinese tourist from Macau was trying to take a photo at Grand Canyon West’s Eagle Point when he stumbled and fell to his death.

A 67-year-old California man was killed April 3 after he fell 400 feet from the edge of the South Rim, near Grand Canyon Village.

Seventeen people died at Grand Canyon National Park last year. It also drew a record-breaking number of guests — 6.4 million.

“Park staff encourages all visitors to have a safe visit by staying on designated trails and walkways, always keeping a safe distance from the edge of the rim and staying behind railings and fences at overlooks,” the National Park Service said in a statement Tuesday.
