[Ans] According to the National Avalanche Center, what is "rain crust"?


Step 1 : Introduction to the question "According to the National Avalanche Center, what is "rain crust"?"



Rain crusts tend to be much smoother than sun crusts. Unlike sun crusts, rain crusts form uniformly on all aspects but rain crusts--like rain--is highly elevation dependent. Typically rain falls at lower elevations and as you ascend through the freezing level the rain progressively turns to snow.



Step 2 : Answer to the question "According to the National Avalanche Center, what is "rain crust"?"



Rain crust forms when rain falls on snow and freezes into a clear layer of ice. Over time, these layers create drainage channels down fall lines. The result is a visible pattern, known as rill marks, which indicates stability.


Step 3 : Other interesting facts related to the question "According to the National Avalanche Center, what is "rain crust"?"



Prolonged rain on new snow forms drainage channels down the fall-line and make a corrugated pattern in the surface snow. These drainage channels (also called "rill marks," are a strong sign of stability). Next Step : We care our friends, so we share answers. If you care Share G +1 / Comment below your answer.
