Coulee bottoms received their heaviest use during spring and summer while ridges received considerable use during winter. All three classes of gradient combined received their greatest use during spring 1974 (Table 15). Gentle slopes received the greatest use of all three classes throughout the report period while the greatest use of medium slopes and the only use recorded on steep slopes occurred during spring and winter. The greatest use of sidehills occurred during spring, fall and winter, while coulee heads received their greatest use during spring and summer (Table 14)..
