Historic Hood River
I’m not sure where this is, but it’s probably 1920s or 1930s. It’s interesting how early we had major electrical transmission lines in this area. Condit Dam, White River, and Powerdale all joined a primitive “grid” one hundred years ago. With the very early generators if there was a system failure power was out until the generator was repaired. When floods damaged old Powerdale pipes I imagine it could be a week or more to restore power. But by 1913 there was a transmission line across the Columbia bringing Condit Dam power to our side of the river, where it tied in with Powerdale and White River.
They understood the same principles of electricity transmission that are practiced today: cover longer distances with high voltage lines, which must be high above the ground because of some basic laws of physics. The high voltage lets you carry the same power at lower currents, which translates to thinner/lighter/cheaper wires. You need a good amount of air between the wire and the ground to reduce transmission losses from the higher voltages. This basic tower design hasn’t changed much in a century.
There are some pretty large buildings in that valley. Can anyone place it?
