Matthew’s Reviews > Staying Alive in Avalanche Terrain, 3rd Edition > Status Update

I learned about the international destructiveness scall and the American relative size scale. Avalanche runout distance was also explained. The previous chapter was about how avalanches flow. The differences between a wet avalanche and a dry avalanche were compared. Dry avalanches are the more dangerous, deadly, and sizeable of the two. The next chapter will focus on terrain.

Ok, obviously with the recent blistering heat I'm going to put this book down until late fall when once again the glorious cooler temperatures come and snow begins to grace our lives. In the meantime I will pick up other adventures.

I'm learning about 'trigger points.' They are invisible areas of poor snow bonding, and responsible for avalanches being so mysterious and unpredictable.

Right now Tremper is explaining about how snow fractures in an avalanche. It depends on the snow-grain bond, friction, and anchors.
