This pano was taken from Mt Diablo state park. The elevation was 3000 feet. I was photographing north. The distance to the river is approx. 12 to 15 miles. In the center of the photo if you zoom in you will see smokestacks. Those smoke stacks are what you see in the black and white photo. I converted the photo because the color version was awful. 60 years ago I use to work at this park as a park aid. This is the first time I have been back.
