Travel along the Oregon and California trails increased in the 1840s with the cry of “Westward Ho.” When the 1848 discovery of gold was made at Sutter’s Mill in California, the desire to reach the gold fields ahead of others intensified quickly, pushing gateways deeper into the frontier and farther north along the Missouri River. Twenty years later, the era of emigrant wagon trains along these routes nearly vanished with completion of the transcontinental railroad. The sudden impact of western expansion resulted in newly revised treaties with local American Indian tribes that opened the Great Plains to settlement. By the 1850s, land surveyors were busy platting and surveying land for new communities in eastern Kansas. In 1857, the nearby community of Gardener was established. Jacob Victor, one of the first settlers to see the potential of this unique location, established a claim to build a hotel near a spring east of here on the Santa Fe Trail. Following the Civil War, freight wagons traveling through the junction to and from Santa Fe became less common as railroad lines quickly spread across the Kansas frontier. Gardner continued to grow through the remainder of the 19th century as routes once used by overland wagons gave way to stage coaches, railroads, farm equipment, and eventually fuel powered motor vehicles. At the outbreak of World War II, the U.S. Navy broke ground on the former Victor homestead to build a Naval Air Station pilot training center. It later became the Command Center for one of the twelve U.S. Army Nike Missile sites in the Kansas-Missouri area. William Sublette’s 1827 discovery of this trail junction did more than help pioneer emigrants find a land route to the west; it established a landmark that otherwise might have been just another stop on the trail. Where the Trails Divide is the city of Gardner's motto, recognizing this important site and Gardner's place in the settlement of the American west.
