AbstractMass casualty incidents (MCIs) are rare in wilderness and mountain settings. Few case studies have reported the response of such events within jurisdictions with well-developed trauma and emergency medical services systems (EMS). Here we explore a MCI in a wilderness setting on the Columbia Icefield inside the Jasper National Park within the Canadian Rocky Mountains. An all-terrain bus was involved that had rolled over while transporting tourists to explore the glacier. The bus rolled multiple times down the slope adjacent to the road, leading to 3 deceased and 21 patients requiring transport. A massive pre-hospital response ensued.Due to the location, extreme environment, and unusual complexities, the response involved significant use of aeromedical resources, physician field deployment, and centralized coordination centers. Readers are reminded of the importance of aeromedical surge capacity in allowing for effective distribution of patients to multiple receiving facilities. Our experience aligns with and reinforces many of the recommendations for wilderness MCI management; however, future research should focus on determining optimal triage strategies for mountain MCIs. Furthermore, future research should explore optimal strategies for developing a rescue chain given the availability of mixed transport resources, as well as the role of physicians in MCI response and where they are best placed in the incident command system.
