Mount Rainier, an iconic stratovolcano in Washington State, boasts impressive summit statistics. With an official elevation of 14,410 feet (4,392 meters), it’s the highest peak in the Cascade Range. The mountain features two volcanic craters, extensive glaciation, and challenging climbing routes. Success rates for summiting vary, with about 50% of climbers reaching the top annually. Weather conditions at the summit can be extreme, with temperatures ranging from -20°F to 40°F and annual snowfall exceeding 600 inches.
What is the Exact Elevation of Mount Rainier’s Summit?
Mount Rainier’s summit elevation has been a subject of slight variations due to geological changes:

Despite the minor difference, Columbia Crest is still widely recognized as the summit. The mountain’s geological features include:
- Two volcanic craters at the summit, each over 1,000 feet in diameter
- A small crater lake in the west crater, the highest in North America
- Over 35 square miles of snow and ice, forming the largest single-peak glacial system in the United States
