There is no historical marker. No sign. No gravestone.
Luckily for me, Chuck Eckman is still agile in his early 80s, setting the pace as we walk up a dirt road and across a mowed hayfield in a swampy stretch of northeastern Minnesota 3 miles west of Moose Lake.
In a stand of birch trees, Eckman stops and leans against an ink-black opening into what, a century ago, served as the Soderberg family root cellar. The 6-foot-high igloo of stone morphed into a mausoleum on Oct. 12, 1918.
When I punch the flashlight app on my phone and step into the clammy cellar's blackness, I'm swept back to one of the darkest years in Minnesota history — and the subject of my new book: "Minnesota 1918: When Flu, Fire, and War Ravaged the State" (Minnesota Historical Society Press).
The three calamities that converged on 1918 Minnesota — fires Up North, war in Europe and the deadly flu pandemic — killed thousands but also revealed the resiliency of everyday Minnesotans. Many of them were immigrants from Finland, Poland, Germany and Scandinavia. The first World War claimed 1,432 Minnesota soldiers in the trench warfare and mustard gas of Europe. Another 2,326 soldiers from the state died in the deadly flu pandemic, which spread through troop transfers in waves across the globe — killing an estimated 50 million people, including roughly 12,000 in Minnesota.
Just as the war ground to an end in France and flu deaths spiked, a bone-dry summer and railroad sparks combined to ignite an October wildfire that killed more than 450 people — leveling the cities of Cloquet and Moose Lake and a dozen other communities in a sprawling burn zone that covered 1,500 square miles in seven northeastern Minnesota counties.
The 1918 fire remains Minnesota's deadliest natural disaster. And more than 100 people lucky enough to survive were crammed into evacuee housing, where they contracted the flu and died.
"The pitiful tragedies and thrilling escapes reported were so numerous," Duluth weatherman Herbert Richardson wrote in a 1919 report, "that any attempt at detailed description of them would fill a volume."
