[6] In 1886, a mystery creature was noted for making livestock kills in the Madison Valley.

A local rancher, Israel Ammon Hutchins, finally shot and killed the beast, after accidentally shooting one of his cattle, which was on the other side of some brush.

Jack Kirby (Hutchins' grandson) tracked the mount to a museum in Pocatello, Idaho, circa 2007.

The 2003 Ennis shooting took place on June 14 of that year, when 44-year-old George Harold Davis opened fire outside the Silver Dollar Saloon bar on Main Street.

He then fled to Missoula County, where he was finally stopped and arrested by police.

[11] The Thexton Ranch is located approximately 7 miles (11 km) south of Ennis, and is listed on the National Register of Historic Places.

Approximately 12 miles (19 km) north of town, the Madison Dam creates Ennis Lake at the head of Bear Trap Canyon.

36.0% of all households were made up of individuals, and 11.2% had someone living alone who was 65 years of age or older.

Ennis is the center of a long-standing ranching economy in the Madison River valley.

Large cattle and sheep ranches dot the valley north and south of the town along the river.

Ennis is also a major tourist attraction and angling destination for fly fishermen targeting rainbow and brown trout.

The small town hosts at least three fly shops and numerous resorts that cater to fly anglers with guided fishing trips on the Madison and in nearby Yellowstone National Park.

Ennis is home to Willie's Distillery, known for its bourbon and moonshine, and one of the growing number of micro-distilleries in Montana.
