Marcus Daly Changed Bitterroot Valley History
Marcus Daly, the copper mining magnate, came to the Bitterroot Valley in search of timber to supply his mines.
Mr. Daly made the valley his summer home in 1887, and changed Bitterroot Valley history in the process.
He acquired large tracts of land termed the Bitter Root Stock Farm, which he devoted to his hobby of breeding and racing thoroughbred horses.
He needed a mill to serve his timber operations and a town to serve the mill.
James Hamilton, a Daly employee, platted the town along the route of the Northern Pacific Railway in 1890.
The town of Hamilton was incorporated in 1894 and was named after Mr. Hamilton.
Hamilton was a company town revolving around the activities of the large Anaconda Copper Mine and the Bitter Root Stock Farm.
Most Hamilton residents worked for Daly business interests, lived in “company” homes and shopped in “company” stores.
By the time Daly died in 1900, Hamilton was the commercial center of the Bitterroot Valley and the seat of Ravalli County.
The Big Ditch
Marcus Daly began development of an irrigation network that, after his death, gave rise to the “Big Ditch Boom” that ran from 1906 through 1915.
The grandiose irrigation and land development scheme was fueled by speculators from the East and Midwest, who invested big money to build the Big Ditch irrigation system.
The subsequent “Apple Boom” was fueled by slick salesmen with often misleading literature who promised fertile land and a good climate for growing fruit trees (mainly apples) which, in turn, brought many unsuspecting farmers to the region.
From 1907 to 1911 the town’s population jumped from 1,800 to 3,000.
The Anaconda Copper Mining Company Mill closed down in 1915 after running out of accessible timber.
By 1917 financial problems plagued the ditch builders and the boom went bust. The orchard farmers became disillusioned and many moved away.
Although the economy went into decline the town survived through farming and timber production.
Truck gardens produced fruit, berries and vegetables, dairies were known for their butter and ice cream. Many farmers grew celery, sugar beets and potatoes.
The U.S. Forest service employed others in their stewardship of thousands of acres of government owned timber land.
A New Beginning
Hamilton’s period of economic decline did not fully recover until 1927 when the Rocky Mountain Laboratory was established to research the cause of Rocky Mountain spotted fever.
Contrary to other parts of the nation, Hamilton enjoyed considerable growth during the depression years of the thirties until World War II.
Many decades later, Hamilton and Ravalli County experienced a period of 40% growth in the late 1990’s and early 2000’s.
The nation’s population was shifting from urban cities to the non-urban “new west” in search of a better quality of life.
People were drawn to Hamilton because of clean air and water, the open space, and the recreational opportunities of the mountains and the streams.
Population growth of the Bitterroot Valley slowed in 2008 for more than a decade, but has been growing again as people continue to seek the quality of life the valley offers.
