Sorry that I can't be of much help to you about photographs of Kelton in Box Elder Co. I have seen one of the town, ca. 1872, but my photos are of some of the people who lived and worked there. In the photo I saw of the town of Kelton, the buildings were in one line, on the same side of the tracks as the spring was. I have never been there, so I don't know if this is much help since the tracks were removed and used for the war effort in WWII (so I have heard.) Since two of my great grandfather Joseph Rosevear's siblings were buried there, I would be interested in knowing which markers are left in the cemetery. At one time there was a marker for John Rosevear, his brother.
I found an interesting story in an old newspaper about the hotel, but before my ancestors owned it--I think. It was described as having canvas on the walls and ceilings to keep the desert dust and dirt from blowing through. Passengers stopping for the night were warned not to fall asleep in the dark lobby because of the large number of bedbugs infesting the hotel!
Let me know what you discover in your search-- both at the location and in writing. There isn't much written about Kelton that I have found. Thanks for writing.
