Those photographs depict an abandoned church in Otto Wyoming, a very small Wyoming farm town in the Big Horn Basin. I don't know anything about the history of the church at all, other than that it once existed and based on a reference I found to it, it was at there at least as early as the 1920s.
Now Otto is just a few miles from Burlington (eleven miles) and Basin (twelve miles). Both Basin and Burlington are larger towns, which isn't to say that they're enormous by any means.

Basin is the more substantial of the two, and is the county seat. Basin isn't far from Greybull, another fairly small town, and Worland, a much larger town.
Now, Basin and Burlington all have churches. Burlington, however, is quite limited in those regards, at least at the present time. It has an Episcopal and a Mormon church. Basin, on the other hand, has a larger representation of denominations.
Now, their could be a lot of explanations for this, but still you have to wonder when it was that tiny Otto required its own church? Perhaps the denomination of the church explained it. Or perhaps 11 or so miles was a long ways not all that long ago, really. Certainly, eleven miles by horse or cart is a very long ways, particularly if you have to turn around and go back the other way, and that's even if the weather is nice. And eleven miles by Model T isn't a short trip either.
