These beautiful works of art are just two examples of the creations produced in the International Snow Sculpture Competition which took place in Breckenridge, Colorado in January of 1998. Sometimes it can be very hard, but it can also be very gently material. Temperature has a great effect on the properties of the snow. When temperature is over 0 celsius degrees snow is very wet and heavy, but it has excellent adhesion force.
Figure presents the value of internal adhesion force of snow in various temperatures.
As we can see, snow is easiest to handle, when temperature is a little bit over 0 degrees. When temperature is below zero degrees, snow is very light and fine material. All moisture has frozen and snow is almost lighter than air. Snow is also very dry now and it's impossible to form any constructions out of snow with traditional methods. Freshly fallen snow is maybe the finest material in the world, but it easily turns to hard and thick material.
