Mr. Ault had helped to avert financial disaster to the agricultural base by purchasing the entire grain harvest during a year of severe economic hardship.

A north–south segment of the railroad connecting Denver, Colorado, and Cheyenne, Wyoming, passes through the town, parallel to U.S. Highway 85.

On February 21, 1910, Rabbi I. Idleson of Denver, Colorado, purchased 640 acres (2.6 km2) for farming purposes near Ault, proposing "to employ Jewish farmers and devote land to practical philanthropy".
