OGALLALA, Neb. (AP) — One of Nebraska’s largest farms will be up for auction later this week.

Thomas Land Co. holds 28,645 acres of ranch and farmland that overlooks Lake McConaughy in western Nebraska.

The auction has drawn interest from more than 500 people already. Scott Shuman with Hall and Hall Auctions in Eaton, Colorado, says he expects the bidders to be a mix of farmers, ranchers and investors.

The farm consists of a ranch operation, irrigated farmland and nonirrigated land. Each one of those segments is big enough to stand alone.

The roughly 45 square miles of land along U.S. Highway 26 is for sale because Michael Thomas died in 2015 at age 74. He was the one who assembled the property.
