1955 Map of Park City East

About this map

Park City stands as the primary industrial hub of this mid-century survey, surrounded by the intense mining activity that defined the Wasatch Range economy. The landscape is marked by substantial operations such as the Ontario, East Ontario, and Judge Mine, while a large Tailings Pond at Richardson Flat reflects the scale of mineral processing. The Union Pacific railroad corridor provides the essential transport link, connecting Keetley and Keetley Junc to the broader regional network. High-elevation valleys like Deer Valley and Frog Valley are mapped before their later transformation, shown here alongside traditional agricultural landmarks like Clark Ranch. The terrain transitions from the open flats of Parleys Park to the complex drainages of Ross Creek and Threemile Canyon, capturing a moment when the area's identity was rooted firmly in extraction and ranching.
