The sight centers on the headquarters buildings of the Guernsey-Frederick Ranch. That these building stand almost in the shadow of Register Cliff is symbolic of the valley's heritage. Here, history emphasizes the Oregon Trail; such other epochs as the storied Cattleman's Frontier are subordinated by memories and the visual landmarks of that nationally famous emigrant road.Since the days of "open range" and "free grass" the Guernsey-Frederick Ranch has been representative of Wyoming's always important livestock industry. The place is, however, also significant in its own right. It brings together two pioneer ranching family names which also relate to such other facets of state history as frontier military life, political activity, governmental organization and the development of railroads, mines, irrigated lands, schools, churches and banks.Favorably located and progressively operated, the ranch is as significant in modern times as ever it was in the past.
