Residents may see a helicopter flying low and slowly along transmission lines June 24-28, depending on weather conditions. The flight will follow power lines from Anderson Canyon in Peshastin to the top of Stevens Pass, and from Coles Corner to Lake Wenatchee and Plain. The flight crew will use Light Detection and Ranging (LiDAR) technology to collect high-definition information about the lines and equipment, and to identify areas to trim back trees and vegetation away from the lines.
