This unusual power line isn't part of the "grid", like most. Instead, it's a single point-to-point line carrying one million volts DC from a large coal-fired plant near Salt Lake down to Adelanto, in Southern California.

This is where it crosses US route 6, near where it starts. Here's the same piece of wire about 400 miles away: http://www.pbase.com/pderocco/image/58875382
