    Collection Overview: NCALM logo This lidar dataset was collected as part of an NCALM Seed grant for Zena Robert at Montana State University. This dataset was collected to help detect changes in hillslope geomorphology due to thawing permafrost in the interior of Alaska. Lidar surveys were conducted north of Fairbanks, Alaska.
