What is new for Northwoods Drifter in 2026
A block north of Wausau’s historic Woodson History Center, three walls of steel and concrete now rise against the winter sky. Inside those walls, 70 years of Marathon County’s stories — thousands of photographs, film reels, lumber-era ledgers, and worn furniture from pioneer families — will finally find a permanent home.
The Marathon County Historical Society is months away from completing the John and Carolyn Sonnentag Archive Center, a 38,096-square-foot facility designed to preserve everything from turn-of-the-century clothing to fragile film footage that’s been sitting in inadequate storage for decades. For anyone who’s ever dug into their family tree or wondered about the loggers and mill workers who built this region, this building represents something bigger than climate-controlled storage.
It’s about keeping the Northwoods’ past accessible for generations who’ll never meet the people who lived it.
Right now, Marathon County‘s historical artifacts are scattered across multiple warehouses and tucked into corners of the existing Woodson History Center. Some items have been stored this way since the society’s founding in 1952, when community members worried that Wausau’s lumber boom history was slipping away faster than white pine through a sawmill.
“We’re consolidating 70 years’ worth of collections into a space actually designed for preservation,” says Blake Opal-Wahoske, MCHS executive director. The new center will feature state-of-the-art climate control, specialized lighting to prevent deterioration, and a cold chill room specifically for film storage — the kind of setup that keeps nitrate film from turning to dust.
This isn’t just about keeping old stuff from falling apart. For researchers, genealogists, and curious locals, the consolidated collection means easier access to city directories dating back to 1897, historical photographs, and newspaper clippings that tell stories you won’t find in textbooks.
Construction kicked off in August 2025, and anyone familiar with Wisconsin building projects won’t be surprised to hear that winter had other plans. Crews faced delays as temperatures dropped and snow piled up — the kind of setback that’s practically written into every Northwoods construction contract.
“We did have some delays due to good old Wisconsin winter weather,” Opal-Wahoske acknowledges. “However, this is not completely out of the scope of things that happen when we do construction in Wisconsin winters.”
Despite the weather, the project stays on track. Interior framing is underway, and over the coming months, the building will take on its finished character with red brick exterior walls and architectural details that nod to Wausau’s historic downtown. The target completion date sits around mid-September 2026, with artifact relocation beginning shortly after.
Marathon County sits at the heart of Wisconsin’s Northwoods, a region defined by its lumber heritage and the rivers that floated logs to mills. Wausau grew from George Stevens’ first sawmill at Big Bull Falls in 1839 into a powerhouse of the white pine industry, then pivoted to paper mills as the forests thinned.
The families who drove that transformation — lumber barons like Cyrus Yawkey, early settlers like Walter McIndoe (known as the “Father of Wausau”) — left behind more than street names. Their letters, business records, and personal belongings fill the historical society’s collection, offering windows into what life looked like when this region was being carved out of wilderness.
Preserving these materials ensures that future Northwoods residents can trace their roots back to the people who built the mills, floated the logs, and transformed pine forests into thriving towns.
For anyone researching family history or writing about the region, the new archive center will make it easier to dig into those stories. The society’s online database already includes city directories and local publications, but having physical artifacts properly stored and catalogued opens up research possibilities that digital scans can’t match.
The scope of the collection is staggering. Walk through the doors when it opens, and you’ll find:
Each item represents a piece of someone’s story. A worn work jacket might have belonged to a mill worker. A ledger could show what goods cost at a general store in 1905. These aren’t museum pieces behind velvet ropes — they’re research materials that help people understand where they come from.
The Marathon County Historical Society has operated from the 1914 Woodson History Center since purchasing it in 1995, offering programs and exhibits that draw locals and tourists alike. The society also maintains the Cyrus C. Yawkey House, a stunning 1900 Classical Revival mansion that landed on the National Register of Historic Places in 1974.
The new archive center expands that mission, creating space for educational programs, research visits, and behind-the-scenes work that keeps history alive. It also supports the kind of community connection that matters in a region where family roots run deep and people take pride in Northwoods identity.
As the building takes shape over the next several months, it’s worth driving past McIndoe Street to watch the progress. Those rising walls aren’t just another construction project. They’re infrastructure for memory — a place where the Northwoods’ past gets the care and attention it deserves, so future generations can keep discovering where they came from and what their communities were built on.
When the doors open in late 2026, the John and Carolyn Sonnentag Archive Center will stand as proof that preserving history isn’t about living in the past. It’s about making sure the stories that shaped this region — the logger who worked the river drives, the family that ran the corner store, the mill owner who built a mansion — don’t get lost when the last person who remembers them is gone.
