At least 16 people have died at the Grand Canyon in Arizona this year, including the recently recovered body of a 71-year-old man at the storied national park this week. The causes of death range from boating accidents to drowning after flash floods. … Meghan Smith, the preventive search and rescue coordinator at the park, cautions that the canyon’s story shouldn’t be boiled down to all doom and gloom. … While climate change has been a major factor in extreme weather events around the globe — including the sort of heat waves and flash flooding that have plagued the park as much as elsewhere in the United States — Smith is wary of drawing a direct link between the string of deaths at the park and a changing environment.
