Prompt
"Generate a realistic image of a massive concrete gravity dam in a desert landscape, with a prominent arch-gravity structure spanning a wide river. The dam, known as Hoover Dam or Boulder Dam, stands 726 feet tall and 1,244 feet long, with a distinctive series of 17 towers along its crest. In the background, a vast expanse of arid landscape stretches out, with the Colorado River snaking its way through the Black Canyon. Incorporate a few visitors or tourists in the foreground to give a sense of scale, but ensure the dam remains the main focus. Style: Photorealistic, with a muted color palette reflecting the desert surroundings."
