Emergency medical services are provided by rangers on duty. Call 911 in case of an emergency.
Medical services are available year round, except some holidays, at Mammoth Clinic (307 344-7965). Services are also offered seasonally in the summer at Lake Clinic (307 242-7241) and at Old Faithful Clinic (307 545-7325).
All of these clinics are open to the public and are staffed and equipped for most medical emergencies as well as for routine care. Services include injury and illness treatment, x-rays, and some lab and pharmacy services.
If in-patient care or advanced services are required, the clinic staff can stabilize patients and arrange for appropriate transfer to a hospital outside the park.

Some groups of Shoshone Indians, who adapted to a mountain existence, chose not to acquire the horse. These included the Sheep Eaters, or Tukudika, who used dogs to transport food, hides, and other provisions. The Sheep Eaters lived in many locations in Yellowstone.
