Pony Express Mail (Valentine Station) - Hartville, WY
Where Mining Grit Meets the Spirit of the West
Established in 1884, Hartville holds the distinction of being Wyoming’s oldest incorporated town. Nestled in the Hartville Uplift, it roared to life as a rugged mining camp after copper was discovered in Eureka Canyon. While neighboring Sunrise was a “company town,” Hartville was the wilder heart of the region, bustling with saloons and an opera house.
This 2026 Valentine Station cachet honors this grit and grace. It celebrates the legacy of the Pony Express, which once galloped through nearby Fort Laramie, carrying vital connections across the frontier. Today, this spirit is kept alive through the annual Valentine’s Day re-ride, a tradition started in 1996 to preserve the local post office. By blending industrial mining roots with the timeless message of the “Spirit of the West,” Hartville continues to deliver love across Wyoming.
