This chromolithographic postcard depicts the eastern entrance to the Zion-Mt. Carmel Tunnel in Zion National Park, Utah, showcasing the impressive feat of engineering carved through the park's signature Navajo sandstone cliffs. The vibrant colorization, likely applied during the printing process by Mike Roberts, enhances the natural beauty of the scene, highlighting the reddish-orange hues of the rock formations against a partly cloudy blue sky. A vintage automobile, possibly from the 1950s judging by its styling, is parked near the tunnel entrance, providing a sense of scale and placing the postcard firmly within the mid-20th century. The composition expertly frames the tunnel's arched entrance and the accompanying bridge, with the road winding through the canyon visible in the foreground. The surrounding vegetation, rendered in varying shades of green, adds depth and further emphasizes the rugged landscape. Published expressly for the Utah Parks Company of Cedar City, Utah, by Intermountain Tourist Supply, Inc. of Salt Lake City, Utah, and bearing the designation C3195, this postcard represents a tangible piece of Americana, capturing a moment in the history of both automobile travel and the development of national park infrastructure. The verso provides a concise history of the Zion-Mt. Carmel Tunnel, noting its construction between 1927 and 1930, its impressive length of 5,607 feet (over a mile), and the remarkable fact that it was hewn from solid rock. This detail adds significant historical context, making the postcard appealing to collectors interested in engineering marvels, transportation history, and the scenic grandeur of the American Southwest. The careful composition, vibrant colors, and historical information offered on the postcard elevate it beyond a mere souvenir, transforming it into a miniature work of art and a valuable record of a specific time and place.
