From The Morning Report Archives

Today’s incident from the Morning Report archives:

Grand Canyon NP – A Japanese tour group stopped at Second Trail View on West Rim Drive around midday on March 13, 1989. Although the tour leader advised group members about the dangers of standing near the rim, a 22-year-old woman moved close to the edge to pose for a photo, lost her balance, and fell backwards off the rim. She fell about twelve feet, then slipped over a ledge and fell another 340 feet to her death.
