   I have been told that another consideration for "shallow" grounds is 
freezing.  Ground rods extending below the frost level will
work better when the top layers of soil are frozen than rods which remain in 
contact only with frozen soil.  However I have not seen
any definitive studies of effectiveness of grounding systems when soil is 
frozen.

   It is a fact that thunderstorms can occur at times of the year when the 
ground is frozen.
