The Grand Canyon of the Yellowstone is a stunning geological feature located in Yellowstone National Park, Wyoming. It stretches about 20 miles long and reaches depths of over 1,200 feet. The canyon is known for its vibrant colors, which are caused by the mineral-rich waters of the Yellowstone River that flow through it. Visitors can enjoy breathtaking views from several overlooks, including Artist Point and Lookout Point. The canyon is also home to the impressive Lower Falls, which drops 308 feet, making it one of the tallest waterfalls in North America. This natural wonder attracts millions of tourists each year.
