History

Historical Context

Modern Grand Canyon heat-avoidance rules echo earlier U.S. heat crises. In July 1995 a nationwide heat wave killed roughly 1,000 people and set a 115 °F record in Phoenix, while the National Park Service logged 109 °F on the South Kaibab Trail. Earlier, the 1901 Eastern United States heat wave claimed 9,500 lives, prompting today’s 10 a.m.–4 p.m. ranger briefings and coordinated mortality tracking.
