Prompt
"Generate an image of a serene and majestic river flowing through a vast, boreal forest landscape with hints of tundra in the distance, under a polar sky with the sun low on the horizon. The Mackenzie River, a significant waterway in Northwestern Canada, should be the central focus, showcasing its tranquil surface reflecting the surrounding natural beauty. Include some subtle hints of the river's importance, such as a small boat or a bridge in the distance, but keep the overall feel natural and untouched. The style should be photorealistic, emphasizing the river's length, its role as a largest river system in Canada, and its flow through the Northwest Territories towards the Beaufort Sea. Capture the essence of its historical significance as a fur trade route and its current importance for transportation, fishing, and wildlife."
