A spokeswoman said it was the first over-the-edge death this year at Grand Canyon National Park, which had 17 fatalities last year.

Two people died at the Grand Canyon late last month in separate incidents that included one man stumbling over the edge of the rim while trying to take pictures at Grand Canyon West, a popular tourist destination on the Hualapai reservation outside the boundaries of the national park.

Grand Canyon National Park is one of the most popular tourist destinations in the U.S., drawing nearly 6.4 million visitors last year. Grand Canyon West on the Hualapai reservation gets about one million visitors annually.
