Big Timber got its name from a railroad official in St. Paul Minnesota after he had read entries from William Clark's journals. The entries describe an area of large cottonwood trees and was originally called "Dornix".
The town became an ideal sheep ranching area and at one time shipped more wool than any other US city. It sits in the valley formed by the Boulder and Yellowstone Rivers and is located in central Montana about 60 miles East of Bozeman. Today it is a successful agricultural area.
The magnificent mountains and western culture have been eyed by Hollywood filmmakers. Both "A River Runs Through It" and "The Horse Whisperer" were filmed in Big Timber.
In 2004, the population was 1,745.
