Mount Vernon is an unincorporated community in the town of Springdale, Dane County, Wisconsin, United States.

[1][2] The "Big Spring" on the Mount Vernon Creek branch of the Sugar River is located in what is now Donald Park.

The "Big Spring" has been known since at least the 1800s and is one of the features that made Mount Vernon an attractive place for settlement.

The cabin is believed to be the home of the George Patchin family who were the first Western settlers in the area after migrating from Ohio in 1846.

Farmers from the region brought grain into town to have it milled and bought supplies from the general store.

They also sold village lots for exorbitant prices to buyers in New York State using false and misleading sales materials.
