The early settlers snatched up the rich, loamy land along the Feather River to grow grapes and orchards. Edward Mathews, an Irishman who fled the potato famine, was peddling vegetables and didn’t have the cash for that kind of soil. During heavy rains, the Yuba River would flow so hard into the Feather at Marysville, it pushed the Feather back north into Jack Slough, named for a freed slave who in 1861 sold Mathews 200 acres of its poor red soil.
