A little history lesson
In the first 10 years of Yellowstone’s life as a National Park it was under serious threat from exploitation. Speculators built camps and hotels right next to the hot springs along with bath’s and laundries in the hot springs for the tourists. People took large pieces of geysers and artifacts from the grounds, while hunters poached animals.
With no one to protect the resources Congress, in 1886, sent in the Army to protect these natural resources. For the first 5 years life was harsh in temporary Camp Sheridan. Soldiers lived in temporary wood framed buildings and tents through harsh winters. In 1890 Congress allocated money for a permanent post, Fort Yellowstone, to be built in the Mammoth Hot Springs area seeing no end in site for the Army’s deployment here. In 1910 there were 324 soldiers stationed here patrolling the park on horse back in summer and skis in the winter.
