The terrain where an avalanche can occur, start to finish.
An avalanche path describes the terrain where an avalanche can occur, from its starting point to its terminus. Classic avalanche paths are obvious, characterized by steep bowls that drain down treeless mountain sides, with mature trees marking the lateral and vertical extent of avalanche flow. Not all avalanche paths are as easy to recognize, though. Some are small features near creek beds or in gladed terrain, and avalanche paths above treeline lack obvious vegetation clues. Essentially any open or gladed snow-covered slope steeper than about 30 degrees has the potential to produce avalanches that can flow into lower angle terrain below.
