South Metro Schools Just Dominated Minnesota's Best for Athletes List

Rosemount came in at #2 in the entire state. Lakeville South landed at #3. Lakeville North at #16. Here's why the south metro keeps showing up on lists like this.

Lakeville Just Opened a Real Baseball Stadium

Belzer Stadium at Grand Prairie Park is a $4 million full-size ballpark with a grandstand, full lighting, and a regulation diamond.

County Road 42 Is Getting Four Lanes

MnDOT, Dakota County, and Rosemount have all been studying it, and the plan is real. Highway 55 gets rerouted, the Highway 52 interchange gets rebuilt, and the two-lane country road becomes a divided highway.

You're standing in an Eagan parking lot. Target, maybe. Or the strip mall off Pilot Knob. Beneath your feet, under the asphalt and the storm drains, there's black soil so rich it once made this suburb the Onion Capital of the United States.

Not Minnesota. The entire country.

THE SWAMP THAT BECAME GOLD

Before any of this was Eagan, it was water. More than 1,200 lakes, wetlands, and ponds scattered across 33 square miles. Early settlers dismissed the marshes as useless.

But beneath those wetlands, something extraordinary was happening. For thousands of years, dead plants had been sinking, decaying, compressing into what farmers call muck: soil so dark it looks like coffee grounds, so rich in organic matter it practically glows with fertility. Perfect for shallow-rooted vegetables that need constant moisture and heavy nutrients. Onions. Celery. Carrots.

THE PEOPLE WHO CAME BEFORE

Around 1750, Chief Black Dog established a Mdewakanton Dakota village at the narrow strip of land between Black Dog Lake and the Minnesota River. About 250 people lived there, following waterfowl and game up and down the river corridor. The lake still bears his name. So does the power plant that sits where his village once stood.

In 1851, the Dakota ceded their land. By 1856, Black Dog's village had been relocated to the reservation at Morton, 100 miles southwest. The wetlands they'd fished for generations were about to be drained.

THE ONION KINGS

The settlers who replaced them came from Ireland, French Canada, Germany, and the eastern United States. Starting around 1840, they drained the wetlands and planted onions. The muck soil was perfect. Yields were enormous. Word spread.

By the 1880s, farmers shipped their harvest by rail to markets across the country. The volume was so staggering that the area earned a title no other place could claim: the Onion Capital of the United States.

For roughly 90 years, from 1840 to 1930, this patch of Dakota County was the center of the American onion trade.

THE END OF AN ERA

Around 1930, it stopped. A few bad harvests hit in succession. Southern growers, with longer growing seasons and cheaper labor, flooded the market. One by one, Eagan's muck farmers gave up onions and sold out.

But the farming tradition didn't die completely.

THE LAST FIELD

William and Katherine Diffley had homesteaded 160 acres in Eagan, building their farm at what's now Dodd Road and Diffley Road. Their descendants kept farming while the world changed around them.

In 1973, fifth-generation farmer Martin Diffley started Gardens of Eagan, one of the first certified organic vegetable farms in the Midwest. He was growing the same crops on the same soil, selling to food co-ops instead of railroads.

Between 1989 and 1992, the bulldozers came. The fifth-generation Diffley land was scraped clean for Pinewood Elementary School and housing developments. The muck soil that had grown onions for 150 years was buried under foundations and sod.

The Diffleys didn't give up. They spent five years farming on 18 different leased properties, then bought land in Eureka Township and started over. In 2008, they sold the Gardens of Eagan name to the Wedge Community Co-op. The farm still operates today, growing organic vegetables for Twin Cities tables. Just not in Eagan anymore.
