In cooperation with the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS), snow data were collected on a monthly basis at Denali National Park and Preserve from November through April at thirteen sites in and around the park. Six of these sites are snow courses, requiring ground measurements, and seven are aerial markers. The information collected for the snow surveys includes snow depth, length of snow core, and sample weight. Snow density and snow water equivalent (SWE) are calculated from the collected data. Aerial surveys are conducted for sites that have no appropriate fixed wing landing area nearby. For the aerial surveys the snow depth is recorded and density is calculated using data from the nearest site.
