Further north, in a valley at the very edge of tree line in the mountains of the Brooks Range, scientists set up a laser-powered LiDAR camera to survey an acre or so. Its highly detailed 3D map of vegetation will provide information on subtle differences in topography and other elements that may allow trees to survive, or not.
