Avalanches

• By Michael and Connor

2
What is it

• An Avalanche is loose snow that falls down a
  mountain side crushing almost everything in its
  path.

3
When it occurs

• Although Avalanches can occur on any slope given
  the right conditions, in the United States
  certain times of the year and in certain
  locations are naturally more dangerous than
  others. Winter time from December to April is
  when most Avalanches occur. The highest number of
  deaths occurs in January, February, and March.

4
How it happens or why

• Snow is deposited in big layers as winter
  progresses. These layers may have unsimilar
  properties and an Avalanche occurs when one layer
  slides on another.

5
Prevention or Protection

• If you are caught in Avalanche yell and let go of
  your ski poles snowboard etc. to make yourself
  lighter. Use swimming motions thrusting upward to
  try to stay on the surface.
