First, the vast majority of people who visit the Grand Canyon each year survive the trip. Since roughly 1880, over 600 people are believed to have died while visiting the Grand Canyon. That works out...
about 12 people
An estimated 600 since the 1870s. That includes 128 in the 1956 TWA and United air collision.
The Grand Canyon is a natural feature; it doesn't employ anyone at all.
