Back in the late 1900's, a frenchman, Marque de Mores, came to Medora with the vision of making the town a major meat packing shipping point. With the financial backing of hi father-in-law, he built a meat packing plant. The plant lasted several years but was not able to stay open year round due to the lack of prime beef. This led to its closing.
The plant was operated by other owners untill it was destroyed in a fire about 1906. As you can see, all that remains is the smoke stack, a boiler and brick building corners. Walking around the plant site, this was a fairly large group of buildings. I would imagine that this work was labor intensive. I say this as there was not the machinery needed to do the work.
