DRIGGS, Idaho — A member of Teton County Idaho Search and Rescue (TCISAR) was killed in a snowmobile accident in the Big Hole Mountains on Sunday.
TCISAR shared via social media that the 63-year-old man involved in a “snowmobile versus tree accident” was Mark Bostleman, who had been with the team since 2018.
“With heavy hearts, we share the loss of one of our own,” TCISAR’s statement reads. “He was a dedicated teammate, a generous spirit, and someone who truly embodied the mission of Search and Rescue. A SAR team member since 2018 and a leading Advisor, he showed up with leadership and humility, grit, and an unwavering commitment to helping others — always ready to serve, train, and support those around him. His personality and character even earned him a designated pizza menu item at Pizzeria Alpino – the Bostleman!”
TCISAR was deployed from Driggs on Sunday afternoon to respond to the scene. The Teton County (Wyoming) Search and Rescue helicopter team assisted with a short-haul mission.
“He will be remembered by his team, friends, and family — not only in Teton Valley but far beyond — for his contributions in the field, kindness, humor, and the sense of community he embodied,” TCISAR posted. “His absence is deeply felt by his fellow SAR members and the many lives he touched throughout this community. Teton County Idaho Search & Rescue extends our deepest condolences to his family, loved ones, and friends. We honor his life, his service, and the legacy he leaves behind. Mark will always be part of this team. In living memory, and in continued service.”
