The elevation of a place tells us how high or low it is in relation to sea level. Gauging the elevation of a huge area like Yellowstone National Park is difficult as the park covers an area of more than 3,400 square miles and features many different landscapes and styles of terrain, including mountains, plateaus, bodies of water, and more.
The general elevation of Yellowstone National Park is 8,000 feet (2,400 m) above sea level, which is the average elevation of the Yellowstone Plateau. The Middle Rocky Mountains that surround Yellowstone National Park have elevations ranging from around 9,000 feet (2,700 m) to 11,000 feet (3,400 m).
The highest point in the entire park is Eagle Peak, a mountain in the Absaroka Range in Wyoming. Eagle Peak has an elevation of 11,372 feet (3,466 m) and a prominence of just 1,847 feet (563 m). The mountain is a popular spot with climbers in Yellowstone but is quite difficult to access, involving long hikes through the wilderness to reach the top. The lowest point of elevation in Yellowstone National Park is Reese Creek, which is situated at a height of 5,282 feet (1,610 m) above sea level.
Other key locations around the park include Mount Washburn, which is the most prominent mountain in Yellowstone and has an elevation of 10,243 feet (3,122 m), and Yellowstone Lake, which is both the biggest body of water in the park and one of the most highly elevated, situated 7,732 feet (2,357 m) above sea level.
The elevation of Yellowstone affects its weather conditions quite strongly. The areas with low elevations tend to have warmer average temperatures in general, while the highest areas like the mountains can have below-freezing conditions with a lot of snowfall. This means that the weather in one part of Yellowstone can be very different to another part and the temperature can vary enormously all around the park.
