Overview

• The Teton County Coroner’s office confirmed on July 23 that 43-year-old Slava Leykind died from an electrolyte imbalance triggering cardiac arrest during his sixth ascent of the June 27 Everesting event at Snow King Mountain.
• Leykind, a Westport, Connecticut banker and father of three, had completed six of the 19 required climbs to match Everest’s 29,029-foot elevation gain before he became unwell late that night.
• Jackson Hole Fire and EMS crews responded at 11:28 pm and rushed him to Eastern Idaho Regional Medical Center, where he passed away on July 2 despite treatment.
• Organizers of the 29029 Everesting challenge and on-site medical teams are reviewing hydration protocols and emergency response plans after investigators noted rapid hyponatremia can closely mimic dehydration.
• Leykind served for two decades as an executive at New York’s CG Sawaya Partners and is being remembered by his wife, Amy Keller Leykind, and their three children for his devotion to family and career.
