Background – Law enforcement in Yellowstone and Grand Teton
Wyoming is blessed with two great national parks: Yellowstone and Grand Teton. Yellowstone claims over 3 million visits a year, while Grand Teton records more than 2.5 million visits. Many visitors camp at one of the park campgrounds or stay at a lodge. It is inevitable that visitors will celebrate, DUIs will occur, and that law enforcement will be there.
Because both parks are federal land, they are patrolled by federal law enforcement. Typically, law enforcement is a national park ranger, although there are also special agents who handle serious felony investigations.
