In the 1840s, the area now known as modern-day Guernsey was a vital rest stop along the Oregon Trail, referred to as the "Emigrant's Wash Tub." Here, pioneers paused to wash their clothes, water their livestock, and take much-needed baths. The North Platte River provided essential resources, making this spot a bustling hub during the westward expansion.

In the 1860s, the legend of the Phantom Ship of the Platte River began to circulate. According to local folklore, a ghostly ship would emerge from a rolling mist on the river, its sails and masts covered in frost. Witnesses claimed that the ship's appearance foretold the imminent death of someone they knew. The first reported sighting was in 1862 by a trapper named Leon Weber, who allegedly saw the apparition of his fiancée on the ship; she passed away later that same day. This eerie tale became an enduring part of Guernsey's cultural heritage, adding a layer of mystery to the community's history.

The town of Guernsey lies directly on the historic Oregon Trail. The Oregon Trail Ruts, now a National Historic Landmark, are the epitome of the trail's physical legacy. Thousands of covered wagons, carts, and Conestogas drawn by oxen, horses, or mules carved deep grooves into the Wyoming sandstone. These lasting impressions are a testament to the hardy pioneers who crossed this mighty country to settle on the West Coast.

Charles A. Guernsey played a crucial role in promoting the construction of the Guernsey Dam on the North Platte River. Completed in 1927 as part of the North Platte Project, the dam was essential for water management and irrigation in the region. The area surrounding the dam later became Guernsey State Park, developed in the 1930s by the Civilian Conservation Corps (CCC). The CCC constructed several high-quality examples of CCC architecture using local sandstone, hand-forged iron, and hand-hewn logs. These structures were designed to reflect and complement the natural beauty of the surroundings. The Castle is one of the most iconic structures in the park, featuring a giant fireplace and winding steps leading to an observation area with panoramic views of the park and reservoir.

Entering the new millennium, Guernsey focused on preserving its rich heritage while fostering community development. Efforts were made to restore and maintain historical sites like the Oregon Trail Ruts and Register Cliff. The town invested in infrastructure improvements and hosted festivals celebrating its unique history and culture, strengthening community bonds.
