Yellowstone Lake, an inland lake in Yellowstone National Park, USA.

Yellowstone Lake: It is the largest inland lake in Yellowstone National Park, with an altitude of over 2,300 meters and a surface area of 352 square kilometers. Its maximum depth is 118 meters, and its only outlet is the Yellowstone River. It is actually the center of the Yellowstone volcanic crater, covering the land of Yellowstone National Park with volcanic rocks and magma erupted from here. This lake is home to rare species such as trumpeter swans and Canadian geese. Yellowstone Lake is the largest mountain lake in the United States and the source of the Mississippi River. The lake is 32 kilometers long, 21.5 kilometers wide, and has a shoreline of 180 kilometers. The average depth of the lake is 24 meters, and the deepest point reaches 100 meters. The water in Yellowstone Lake is clear and can be seen to the bottom. The lake water flows into the Yellowstone Grand Canyon through a gap, roaring down and forming the famous Yellowstone Falls. Yellowstone Lake is about 20 miles long and 15 miles wide, nestled in dense forests and snowy peaks. The lake is not deep, only 200 to 300 feet deep. When the wind is calm and the waves are calm, Yellowstone Lake is a beautiful mirror reflecting the forests and mountains. Countless birds such as trout, swans, pelicans, geese, ducks, and herons search for food in the lake and on the shore. Forest animals also come out of the jungle, wading on the sandy shallows, drinking water, looking around, and cooling off in the breeze.
