The Sieben Ranch and Hilger Hereford Ranch are among eight ranches along the Lewis and Clark Trail that will recieve interpretive displays.
According to officials with Montana's Undaunted Stewardship program, displays will be free and open to the general public.
The displays should be completed in about a year, said organizer Steve Pilcher. They were written by Tom Daubert of Helena, and will tell visitors about each area's history, along with past and present stewardship practices in the areas.
The display at the Sieben and Hilger ranches will be installed on a turn-off on the road leading to the lower Holter Lake. The ranches border the "Gates" that Meriwether Lewis named on July 19, 1805.
Undaunted Stewardship is a program managed by MSU-Bozeman, the Bureau of Land Management and the Montana Stockgrowers Association.
It certifies qualifying ranches as "Undaunted Land Stewards" for adhering to sustainable grazing and land management practices.
It also helps preserve historic sites on private land, helps ranches develop side tourism businesses and conducts educational programs about rangeland stewardship and the environmental and cultural benefits of ranching.
The other selected ranches include Mission Ranch, east of Livingston; Beaverhead Gateway Ranch, north of Dillon; Ayrshire Dairy on the southern edge of Great Falls; ABN Ranch along the Missouri River near Loma; Lanning/Terry Ranch, bordering the Missouri River near Big Sandy; Pavlovick Ranch at Judith Landing; and Hamilton Ranch on Carroll Hill between Dillon and Bannack.
