Short summary
Snow avalanches pose substantial risks to communities and public safety in Colorado. We studied tree growth patterns impacted by avalanches from 1698 to 2020 alongside meteorological data. We found variations in avalanche frequency revealing a decline in regional avalanche activity and shifts in the causes of these types of large and widespread avalanche events. This knowledge can enhance avalanche safety measures and infrastructure design.
