Chart IX. Average rainfall during growing season (May, June, July and August). 



Chart X shows the average annual depth of snowfall. Here again 

 the effect of Lake Superior is clearly brought out. The heaviest snow 

 occurs along its shores where the moisture-ladeued air comes in con- 

 tact with the cold land areas and the moisture is condensed into snow- 

 flakes. Snow piles up to great depths along the shore, and several miles 

 inland, decreasing gradually away from the lake.
