A tree well, also known as a spruce trap, is the space around a tree under its branches that does not get the same amount of snow as the surrounding open space. This creates a void or area of loose snow below the branches and around the trunk that is dangerous to any hikers, snowshoers, skiers, snowboarders, and snowmobilers who fall into them.
