<br />cold season (September through April) was plotted for each of the 10 <br />years (fig. 9). Compare figure 10 with figure 9 and note the total <br /> <br />amount of cold season precipitation for all 11 stations for the same <br />10 years. No apparent correlation exists between the actual precip- <br />itation and the number of seedable upslope conditions.
