Mammoth in Mammoth Hot Springs in Park County, Wyoming — The American West (Mountains)
At Guard
Park roads were once aligned so that the guardhouse controlled traffic into Yellowstone from the north. Here soldiers contacted each party and entered the name of the driver, passengers, and type of rig into a large ledger. Guns not held at the guardhouse were sealed on the spot. They were checked at each outpost enroute, where soldiers certified on a form that the seal remained intact. Before visitors left the park, the form was scrutinized at an exit station.
