DULUTH — Minnesota virtually depleted its immense supply of iron ore to assistance the Allies win Globe War II, supplying a fantastic deal of the crucial raw material behind America’s tanks, warships, guns and ammunition.

Reader Jim Herzog wanted to know just how a fantastic deal the Mesabi Range mines contributed to the “arsenal of democracy.” He sought answers from Curious Minnesota, the Star Tribune’s reader-powered reporting project.

The speedy answer is that Minnesota’s wealthy iron deposits had been a really essential element of America’s war perform. About 70% of the iron ore that America devoted to the war came from Minnesota, amounting to added than 333 million tons, according to Pam Brunfelt, a retired Vermilion Neighborhood College faculty member and historian.

“Devoid of the Iron Range, we would not have won the war,” described the Britt, Minn., native, who is writing a book about the phenomenon. “It was just the most astonishing accomplishment.”

Steel production in America tripled from 1938 to 1943. In 1942 alone, America created about eight,000 warships, 24,000 tanks, 48,000 military airplanes and 667,000 machine guns, according to Marvin G. Lamppa’s “Minnesota’s Iron Nation.” Substantially of the raw material to make these armaments came from the Iron Range.

The country’s want for all that all-organic iron ore all through the war practically depleted Minnesota’s deposits and led to the mining of taconite, the reduce-grade mineral created on the Range at present to make steel.

A breathtaking pace

The wealthy deposits of the Cuyuna, Mesabi and Vermilion ranges formed added than two billion years ago when iron eroded from mountains into an inland sea that covered the Arrowhead location. It was sooner or later exposed to oxygen and formed layers of compacted iron sediment.

Minnesota’s Iron Range featured the key iron ore-creating mines in the nation in the early 20th century, assisting to construct structures like the Empire State Constructing. The place was keenly positioned to lead the way all through the war in iron production, with entirely equipped open-pit mines that could ship material conveniently by way of a railroad approach and docks at Two Harbors and the Twin Ports.

“The infrastructure was there to make it take location,” described Ron Hein, a retired Erie Mining executive who co-authored the book “Taconite: New Life for Minnesota’s Iron Range, the history of Erie Mining Company.” “We had the raw material and manufacturing base to convert from peacetime manufacturing to war time manufacturing.”

The very good want for labor and military personnel led Iron Range females to enlist in war efforts when they had been authorized by Congress, as properly as operate in the mines for the really 1st time.

Mining firms opened new mines and expanded existing ones, in some situations excavating added than one particular hundred feet below ground to attain ore. The Mesabi’s oldest mine in Mountain Iron, which had create into a lake by 1943, was even drained and reopened.

Wartime propaganda touted the worth of the Range. A 1943 Exceptional Northern Railway magazine ad, for instance, declared the location and its iron “added really essential than gold” to winning the war.

In a single 24-hour period in August 1943, added than 120,000 tons of ore had been loaded onto 245 trains headed east to the hearths and blast furnaces of steel mills, Brunfelt described. Empty and loaded trains traveled in and out of the Hull-Rust-Mahoning pit in Hibbing every single and just about every three minutes.

Miners and dock workers raced to hold up with the breathtaking pace, from time to time laboring about the clock even by way of winter months.

The Minneapolis Star wrote in 1943 that thousands had been operating by way of “sub-zero cold and driving snows, day and evening … preparing for the greatest movement of iron ore that man has torn from the earth in a single year in all human history.”

These efforts broke iron ore shipment records for the complete Lake Superior location in 1941 and 1942, according to a 1943 challenge of Skillings Mining Critique, printed in Duluth.

“Undoubtedly the 1942 record of shipments was an achievement that was undreamed of a couple of years ago,” the story study, citing added than 93 million tons moved by ship and rail that year.

It was 19,000 occasions what was created in the Range’s really 1st year, five decades earlier. But that total would not be topped as soon as once again.

A depleted resource

Stakeholders knew that larger-grade iron ore on the Range was finite. But several had been confident supply would withstand the war.

“Mr. Hitler is wasting his time. The marvelous tiny Mesabi tends to make it not probable for him to win,” mining booster Arthur Dudley Gillett described in 1943, according to the book “Minnesota Goes to War” by Dave Kenney.

But when the war ended, “the rusting wreckage of steel formed from Iron Country’s mines lay strewn across the planet — smashed and broken tanks, trucks, ships, guns. … And most of Minnesota’s all-organic iron ores had been gone,” Lamppa wrote.

Brunfelt’s father and grandfathers had been miners. She recalls hearing worries about the eventual depletion of iron ore and what that would imply for the future of Iron Range communities.

“Taconite turned that about,” she described.

Absolutely, investigation on how to extract and course of action low-grade iron ore — taconite — had been underway for years, spearheaded by Edward W. Davis, a University of Minnesota professor. New technologies led to steel firms constructing taconite mines and mills in the 1950s and 1960s.

Persons at the time believed that taconite had saved the Iron Range, Jeffrey T. Manuel wrote in “Taconite Dreams.”

But it had consequences, he wrote, which incorporates the closure of mines that could not compete and years of environmental pollution from tailings dumped into Lake Superior. That resulted in a blockbuster lawsuit against Reserve Mining Company in the 1970s.

The Iron Range’s mining business enterprise is smaller sized sized at present. Some empty mines have been reclaimed for new use, such as the Redhead Mountain Bike Park in Chisholm. Redhead Mountain is a 25-mile trail that travels by way of the rugged red earth along open pits filled with water.

Mining on the Mesabi Range remains a big element of the United States’ story, described Jordan Metsa, a spokesman for Chisholm’s Minnesota Discovery Center. It continues to aid the international economy, he described, but its prior — every single in assisting to construct the nation and in aiding war efforts — deserves added recognition.

“Forty-three several ethnicities came to the Range to mine the ore,” he described. “The operate they did to win Globe War II gives me goosebumps. It is a single of the most underestimated stories in America.”
