Dataset Overview: PI: Kristin Gardner, Montana State University. The survey area is a 249 square kilometer irregular polygon located 21 kilometers west of Big Sky, Montana. Seven flights were made beginning on September 20, 2005 and completing on September 25, 2005. Data were collected to investigate spatial and temporal patterns of nitrogen export and land use change in a mountainous watershed.
