In what state is the Grand Canyon located?

The Grand Canyon is located in Arizona, which is known for this iconic natural landmark that spans approximately 277 miles in length and reaches depths of over a mile. The canyon is a significant geological and tourist site, attracting millions of visitors each year who come to observe its stunning vistas and diverse ecosystem. Arizona's designation as the state home to the Grand Canyon is a crucial aspect of its identity, showcasing the unique natural features that are emblematic of the American Southwest. The other options—California, Nevada, and Utah—are states that have their own distinctive national parks and natural landmarks, but none possess the Grand Canyon, making Arizona the only correct answer.
