<br />") <br /> <br />'i <br /> <br />Several SNOTEL sites were considered for the control group. To eliminate the <br />possibility that any of the sites had been influenced by seeding, only those sites northwest <br />through west through southwest were evaluated. For the 1992-93 seeding season Tower <br />Pillow and Lynx Pass Pillow were chosen for this group as they provided the highest <br />correlation during the 28 years non-seeded period from 1965-1992. These sites were <br />used to evaluated the 1994 seeding period as well. <br /> <br />The control and target area stations are shown on Figure 5.
