Why are tree wells so dangerous?

Tree wells are dangerous due to snow-immersion suffocation (SIS). A tree well forms when snow accumulates around the base of a tree, but not under the lower branches or around the trunk. This snow, much like an avalanche, can trap the skier and leave them without fresh air to breathe, thus leading to suffocation.
