 This is because the power lines here run through forests of conifer trees which appear dark green-green from space.The land through here has been logged and sometimes clear-cut to create a right-of-way for the power lines because a wildfire could start when an electrical arc occurs between the wires and a tree if they come close enough to each other.This TANC 500 kV power line, unlike its PG&E counterparts, is triple-bundled, meaning that it has three-wires per phase, whereas the PG&E lines are only double-bundled, or two wires per phase.
