She Wore a Yellow Ribbon is a classic western movie directed by John Ford and released in 1949. The movie stars John Wayne as Captain Nathan Brittles, a cavalry officer who is about to retire after 40 years of service. The movie is known for its stunning cinematography and beautiful landscapes, which were filmed on location in Monument Valley, Utah and Arizona.

Monument Valley is a region of the Colorado Plateau characterized by a cluster of vast sandstone buttes, the largest reaching 1,000 feet above the valley floor. The area has been featured in many western movies and is considered one of the most iconic locations in the American West. She Wore a Yellow Ribbon was the second movie filmed by John Ford in Monument Valley, after Stagecoach in 1939.

The movie was also filmed in other locations in Utah and Arizona, including the San Juan River, Mexican Hat, and Kayenta. The production crew had to face many challenges during the filming, such as extreme weather conditions and difficult terrain. However, the result was a visually stunning movie that captured the beauty and grandeur of the American West.

She Wore a Yellow Ribbon was a critical and commercial success, and it is still considered one of the best western movies ever made. The movie was nominated for two Academy Awards, including Best Cinematography, and it inspired many other filmmakers to use Monument Valley as a filming location. Today, Monument Valley is a popular tourist destination, and visitors can explore the same locations where John Wayne and the rest of the cast and crew filmed this classic movie.
