Jackson resident Gary Sternberg, 69, collapsed and died while cross-country skiing near Phelps Lake in Grand Teton National Park.
The call for help came in at 1 p.m. Wednesday after two of his skiing partners had started CPR, a park press release said.
“Rangers responded and arrived on scene to provide advanced life support, including CPR for approximately 45 minutes,” the release said. “After prolonged resuscitation attempts, CPR was terminated.”
Sternberg died of an unknown medical issue, according to the release.
He spent 26 years working full time and three years working part time for Teton County School District No. 1. Sternberg started his career there driving buses and retired in 2017 as route coordinator for the district’s transportation office. Before that, he worked at Teton Cyclery, and then opened his own business, Sternberg Cycles, which he supported by driving school buses. He built bicycle frames as well as offering repair and maintenance.
