Helene has impacted Appalachian life in extreme ways for the foreseeable future. In addition to catastrophic flooding, deadly landsliding occurred in numerous areas. The Garren Creek community of Buncombe County, North Carolina, may have been the area most severely affected by landslides. Huge debris flows claimed many lives in this area, and while the story has appeared on national news outlets, it has not received the attention that more populated areas have. This video talks about the disastrous debris flows in this area and how debris flows work in general. The video contains information for first responders about the risks of working in a debris flow area following the first pulse, as well as for mountain residents who may live in areas that could be hit by debris flows.
