Lubricating Layer 2


Lubricating Layer 2 : The snow layer involved in avalanche release which, due to its weak internal strength and/or poor bonding to adjacent layers, facilitates the mechanical failure of a snow slab. Two examples of this lubricating layer are graupel or light, wind-deposited snow sandwiched between two more cohesive slab layers. A clearly defined lubricating layer may not always be present in a slab avalanche release
