I was driving up Lolo Pass Road, which goes from Welches to the Hood River Area, one day. Part way up the road, the view opens up as some high voltage power lines and the road zig zag over each other for a short distance.
When I saw this scene, I had to have a photograph of it. I returned to the little store at the bottom of the hill on Hwy 26 and picked up one of those little disposable cameras. I returned to the power line area and took this photograph.
Just turn North off of Hwy 26 on McGee Creek Road in Welches and stay on it. The road turns into Lolo Pass Road and starts to climb a little. When you see the power lines you know you are close. Keep your eyes on the road ~and~ to the right and this scene will appear. It is perhaps 15 miles up the road, next time I am in the area, I will get more specific location information.
If you look closely at the Google Map imagery here, you can see the fine little power lines crossing back and forth across the road. Zoom out for a wider view.
