An imperfect plate. I have some bad film. The dust isn't "dust" it's an emulsion problem.
The Gabbs pole line road is an improbable span of power line poles across a barren waste from nowhere to nowhere. It was necessary for the production of magnesium during the war effort of WWII. I often use this road on travel to Northern Nevada simply because it is empty. You have to endure 46 miles of dirt road to enjoy the solitude but it is the shortest route, and during crazy times, perhaps the best.
The lens is a Turner Reich 12" on full plate.
