Keweenaw Snow Paver
Where Have We Come From?
KRC has developed a new system for grooming that changes
the crystal structure of the trail base to optimize the bonding
and strength characteristics of the trail. This system is the
result of years of research. The final product is a snow
"pavement" with qualities far superior to any method
currently on the market!
How Do We Do It?
The "KRC" groomer uses a milling process to optimize the
surface energy and bonding potential of individual crystals.
Coupled with this change in structure is an optimization of
crystal size mixing. Following this manipulation of snow
properties is a leveling process and maximization of compactive
effort through vibratory compaction.
An attribute of this system that would be quite advantageous to
both Nordic and Alpine Ski areas is that it is capable of turning
ice back into snow. In the absence of compaction, the milled
snow has a texture similar to man-made snow. The advantage of
this is that an icy ski trail could be groomed and the surface
would become soft snow!
