The pic i took today is facing southwest. I think the pic you posted is facing due west. That's about the only direction that there isn't some higher ground that would be in the pic. The bar is right at the intersection with the hiway. The road to Atomic City (1mile) angles off the hiway. I'm not sure Atomic City existed in 1942, so that road would have been dirt probably Midway was called that because it is just about exactly halfway between Arco and Blackfoot. What is now the Idaho National Laboratory was probably just becoming a Federal site early in WWII. They tested naval ship guns there by firing them at the Big Southern Butte about 16 miles to the south of Midway. The desert also became an aerial gunnery range later on in War II. Eventually the Site became a nuclear research center, and the Navy trained their nuclear operators there for many years. Arco was the first city in the world to get their electricity from nukes, though it was only a short-term test.
