Overview
- A female climber was attacked by yellowjackets while descending Redoubt Wall and developed a systemic allergic reaction that left her unable to hike out, search‑and‑rescue agencies said.
- Initial emergency calls reported more than 100 stings but Lions Bay Search and Rescue later told reporters the climber likely sustained roughly a dozen to 20 stings while still suffering widespread hives, dizziness and breathing difficulty.
- A Lions Bay ground team brought emergency medical supplies including epinephrine and then requested a helicopter extraction by North Shore Rescue because the terrain and heavy tree canopy prevented a foot evacuation.
- Rescuers were lowered to the scene to assist a hoist through the canopy and the patient was handed off to BC Emergency Health Services for hospital care.
- Agencies warned that late‑season wasp activity can make even a small number of stings dangerous, urged backcountry users to carry epinephrine and an emergency comms device, and noted that rising wasp populations have increased the risk of similar incidents.
