A whisper of history hangs in the air. This is the Twin Cities Army Ammunition Plant Site Gravel Pit.
Before you stands a seemingly ordinary gravel pit. Yet beneath the surface lies a legacy forged in the fires of World War II. This unassuming site is inextricably linked to the colossal Twin Cities Ordnance Plant. Built in 1941 the plant sprawled across 2400 acres. It employed 26000 Minnesotans. That’s about 1% of the state’s population at the time. A remarkable fact considering the plant’s rapid construction. Completed in just six months it initially housed 100 buildings. This number eventually ballooned to 262.
The Twin Cities Ordnance Plant wasn’t just about numbers. It was about opportunity. It became a beacon of integration. The plant hired over 1200 African American men and women. This represented over 20% of Minnesota’s Black population. This was a significant step in a time of pervasive racial segregation. The plant’s integrated workforce was a testament to the leadership of Charles L. Horn. Horn was the president of the Federal Cartridge Corporation. He famously refused to segregate workers. His stance was supported by Cecil E. Newman a Black civic leader and newspaper publisher. Together they championed equality at the plant.
The plant’s commitment to fairness earned it recognition. In 1943 it received the Army-Navy “E” Award. This prestigious award recognized excellence in munitions manufacturing. It also highlighted the plant’s adherence to fair labor standards.
Beyond its wartime production the Twin Cities Army Ammunition Plant faced environmental challenges. The dumping of industrial waste resulted in soil sediment and groundwater contamination. This led to the designation of a Superfund site in 1983. Extensive cleanup efforts followed. This included groundwater extraction and air stripping. Millions of gallons of contaminated water were treated. The remediation process continues even today.
So the next time you see this gravel pit remember its rich past. It’s a silent witness to the immense effort during World War II. It’s a reminder of a pivotal moment in Minnesota’s history. It’s a testament to the power of integrated workforces and their contribution to victory. This gravel pit is more than just gravel. It’s a piece of American history.
