What is Avalanche terrain? We sometimes use slopes steeper than 30 degrees as a ballpark. But in reality each problem has its own range of steepnesses that cause it to react. Many “basal facet persistences” (what we have in Colorado) regularly react on bed surfaces down to 32-34. But many storm slabs take a much steeper angle, many times approaching 40 degrees. The nuance matter, in this case let’s talk about the nuance of “avalanche terrain”. Here’s an interesting video from last season that do
