Mount Rainier, an iconic stratovolcano in Washington State, is often mistaken for the highest mountain in the contiguous United States. This misconception stems from its impressive stature and prominence in the Pacific Northwest landscape. However, while Mount Rainier is indeed a towering peak, it does not hold the title of the highest mountain in the lower 48 states. This article will explore Mount Rainier’s height, location, and significance, addressing the question: is Mount Rainier the highest mountain?
Is Mount Rainier Actually the Tallest Peak in the Contiguous United States?
No, Mount Rainier is not the highest mountain in the contiguous United States. That distinction belongs to Mount Whitney in California, which stands at 14,505 feet above sea level. Mount Rainier, however, is still an impressive peak and holds several notable records:
- Highest mountain in Washington State
- Most topographically prominent mountain in the contiguous United States
- Most glaciated peak in the lower 48 states
Mount Rainier’s elevation has been measured at:
- 14,410 feet (based on the 1956 survey)
- Recently updated to 14,389.2 feet for Columbia Crest and 14,399.6 feet for the SW Rim (based on 2024 surveys)
These measurements place Mount Rainier as the 17th highest peak in the contiguous United States.
Where Exactly Is Mount Rainier Located?
Mount Rainier is situated in the Cascade Range of the Pacific Northwest. Its precise location is:
- GPS Coordinates:
- Columbia Crest: 46.852950, -121.760572
- SW Rim: 46.851731, -121.760396
The mountain is located approximately:
- 59 miles (95 km) south-southeast of Seattle
- 60 miles (97 km) southeast of Tacoma
Mount Rainier is the centerpiece of Mount Rainier National Park, which was established in 1899 as the fifth national park in the United States.
What Makes Mount Rainier a Challenging Climb?
While Mount Rainier may not be the highest mountain in the contiguous United States, it presents unique challenges to climbers. Several factors contribute to its reputation as a formidable ascent:
-

-
Elevation Gain: Climbers must ascend over 9,000 vertical feet from the trailhead to the summit.
-
Technical Skills Required: Even the ‘easiest’ routes require glacier travel skills and experience with crevasse rescue techniques.
