A female clmber was airlifted from the Redoubt Wall near Lions Bay on August 25 after suffering more than 100 wasp stings. Lions Bay Search and Rescue coordinated with North Shore Rescue to perform the emergency extraction from the rugged terrain.
The 100-Sting Emergency at Redoubt Wall
Lions Bay Search and Rescue received a report on Tuesday evening, August 25, regarding a climber located on the Redoubt Wall near Loggers Creek. According to a Facebook post from Lions Bay Search and Rescue, the individual had been subjected to a massive wasp attack, resulting in more than 100 stings.. The sheer volume of stings elevated the situation from a standard backcountry injury to a critical medical emergency.
The urgency of the response was driven by the risk of anaphylaxis or a severe systemic reaction. Because the climber was in a remote area, the potential for a rapid decline in health meant that every minute counted. Lions Bay Search and Rescue immediately deployed a ground team equipped with essential medical supplies, specifically including epinephrine to counter a possible allergic shock .
Why North Shore Rescue deployed a helicopter to Loggers Creek
While ground teams were moving toward the site, it became evident that the climber could not safely hike out of the Redoubt Wall area on her own. As reported by Lions Bay Search and Rescue, the location was deemed inaccessible for a standard walking evacuation, prompting a request for aerial support from North Shore Rescue.
North Shore Rescue responded by deploying a helicopter carrying a specialized team, which included two advanced medical providers and one technical rescue member. The complexity of the extraction was increased by the environment; rescuers discovered the climber positioned beneath a heavy tree canopy, which necessitated precise helicopter maneuvering to reach and secure her before she could be lifted to safety.
How epinephrine and medical providers managed the Redoubt Wall crisis
The deployment of advanced medial providers from North Shore Rescue was a strategic necessity given the biological nature of the emergency. In cases involving over 100 stings, the body can experience systemic toxicity even in individuals who are not previously allergic to wasp venom. The presence of epinephrine on the ground and in the air ensured that the team could stabilize the climber immediately upon contact.
This incident mirrors a broader trend of late-summer backcountry hazards in British Columbia, where wasp populations peak in August. For outdoor enthusiasts,the Redoubt Wall incident serves as a stark reminder that insect encounters are not merely nuisances but can evolve into life-threatening medical events that require institutional rescue resources.
What triggered the swarm beneath the tree canopy?
Despite the successful extraction, several details regarding the encounter remain unverified. it is currently unknown whether the climber accidentally disturbed a hidden nest beneath the tree canopy or if the swarm was an anomalous occurrence. Furthermore, the source does not specify if the climber had a known allergy to wasps or if the systemic risk was based solely on the quantity of stings.
The report provided by Lions Bay Search and Rescue focuses on the logistics of the rescue rather than the cause of the attack. Without further statements from the climber or a detailed environmental survey of the Redoubt Wall site, the exact catalyst for the swarm remains a mystery.
