A Michigan man died Sunday after suffering a heart attack during a hike in Grand Teton National Park in just one of several incidents that kept emergency personnel busy throughout the park.
A 74-year-old man visiting the park from Troy, Mich. was on a ranger-led hike at Swan Lake near Colter Bay when he was stricken with a heart attack at about 2:15 p.m., according to a statement released Monday by the park’s public affairs office.
