Some AgJ likely reached <br />Berthoud Summit, with 14.2 ppt, and Sundance, with 11.9 ppt. It is possible that some or all 7 <br />target sites with concentrations greater than, say, 5 ppt, received some limited amounts of the AgI <br />seeding agent. But again the concentrations are too low to expect meaningful snowfall <br />augmentation at most sampling locations. <br /> <br />The only target location with Ag levels as high as expected from routine seeding was <br />Michigan Creek with 112.5 ppt from the original sample. A second sample was collected from <br />each snowpit, about 1 ft horizontally from the first, and stored frozen in another location. This <br />18 <br /> <br />
