Prompt
"Generate a serene landscape image of the Aniak River, a 153-mile-long river located in Alaska, United States. The river should be depicted flowing through the Yukon-Kuskokwim Delta, with the Kuskokwim Mountains in the background. Include a few rafters or fishermen on the river to highlight recreational activities such as rafting and fishing. The image should also feature some Arctic grayling jumping out of the water to showcase the river's notable species. The style should be realistic and similar to a nature documentary photograph, with muted colors and soft lighting to capture the tranquility of the Alaskan wilderness."
