THE LITTLE ROCKY MOUNTAINS
Many Indian people believe that spirits dwell in north central Montana's "island" mountains: the Sweet Grass Hills and the Bears Paw and Little Rocky ranges. Their rugged peaks, clustered like tepees in a camp, offer access to the supernatural and provide a nesting place for eagles, the messengers of the spirits who lived there. Generations of Blackfeet, Gros Ventre, Assiniboine, and Chippewa-Cree have used these isolated areas for fasting, prayer and vision questing. *Here are the precious gifts of water, plants, animals, and solitude from the Great Spirit. Stories describing the supernatural powers of the Little Rocky Mountains abound. One such story, handed down in many variations, tells of a terrible water-monster called Bax'aa that inhabited the spring on Eagle Child mountain, frightening or even slaying some who attempted to fast there. Another well known site at the western end of the Little Rockies is a battleground remembered among northern Montana tribes for its spiritual significance. The great Gros Ventre warrior Red Whip won victory there over the Sioux against incredible odds. His success is attributed to a powerful war charm and a vision that foretold the battle.

The History of the Montana Historical
Highway Markers
[It was a man named Bob Fletcher whose idea it was, in 1935, to produce roadside signs which imparted knowledge of Montana's history, each sign containing a bit of the story of some local event or site.] The rustic-looking sign boards were mounted on lodgepole pine posts and hung from decorative routed crossbeams. The posts were set in fieldstone bases to make them eye-catching, rustic—and crash resistant. The sign texts were hand-lettered on five-by-eight-foot plywood boards set in log frames. The first marker, "Gates of the Mountains," was installed on U.S. Highway 91, about sixteen miles north of Helena, in early July 1935. It was followed by twenty-nine more signs by the end of the year.

Bob Fletcher's success in promoting and developing the tourist industry in the early 1930s enabled him to pitch a project that he'd been considering since the 1920s: roadside highway markers that described and celebrated Montana's colorful history. This idea allegedly originated after he became bored reading the historical markers installed by the Daughters of the American Revolution along South Dakota's roads in the mid 1920s. He felt he could do better in Montana by making the marker texts big enough to read from a car "and sometimes humorous." Fletcher later recalled that the texts "should not be a lot of stilted copy with dates and all. I wanted them to be like a native standing there and telling you about the place."

By the early 1950s, severe weathering of the signs compelled the department to begin routing the texts onto redwood boards. By 1952, the highway department had installed over one hundred markers along Montana's highways. Although Montana's historical highway marker program was not the first of its kind in the United States, it proved among the most influential. According to one newspaper article, twelve other state highway departments requested copies of the marker plans.

By the early 1980s, the interstates had diverted much of the traffic off the two-lane highways and onto the four-lane superhighways. Although some signs had been reinstalled at interstate rest areas, most had simply been forgotten, vandalized, stored in maintenance shops, or allowed to deteriorate next to bypassed highways. In 1985, the Forty-Ninth State Legislature allocated $200,000 to refurbish the 132 old markers (the original markers cost $400 each—including the support posts and field-stone bases!) and write twenty-four new ones.

Since 1985, over one hundred new historical markers have been added, covering a wide variety of subjects and styles. The markers have been printed on sturdy, weather-resistant plastic since 1999.
