California leads all US states with over 300 named mountain ranges, according to USGS data. Nevada ranks second with 272, followed by Alaska with approximately 268. Arizona and New Mexico round out the top five. The exact counts vary slightly by source and methodology, but the top-five order is consistent across USGS-based rankings.
How the Rankings Were Determined
The figures here come from the United States Geological Survey (USGS) geographic names database, which tags geographic features by type. Analysts sorted entries tagged as “range” by state to produce a count.
The 5 US States with the Most Mountain Ranges
1. California – 300-plus Named Ranges
California holds the top spot with more than 300 separate named mountain ranges according to USGS data. The state’s terrain runs from the coast to high desert, and its mountain geography is genuinely diverse.
The Sierra Nevada is the most significant single range, stretching roughly 400 miles and containing Mount Whitney, the highest peak in the contiguous US at 14,505 feet (4,421 meters). California’s mountain ranges also include the Coast Ranges and parts of the Cascade Range.
Key national parks tied to California’s ranges:
- Yosemite National Park
- Sequoia National Park
- Kings Canyon National Park
- Devils Postpile National Monument
The Marble Mountains, accessible via Happy Camp, are part of the Pacific Crest Trail corridor and represent the quieter end of California’s mountain offering.
2. Nevada – 272 Named Ranges
Nevada’s range count honestly surprises a lot of people. The state’s Great Basin geography, high desert divided by north-south trending ridgelines, is exactly the kind of terrain that produces a high number of distinct named ranges. USGS counts 272; Explore.com puts the figure at 314, with 35 peaks topping 10,000 feet.
Notable ranges and peaks:
- Ruby Mountains – known for alpine lakes and wildflower meadows
- Snake Range – home to Great Basin National Park and Wheeler Peak
- Boundary Peak – Nevada’s highest point at 13,140 feet (4,005 meters)
Nevada’s average elevation is 5,500 feet (1,680 meters), which gives a sense of just how elevated the baseline terrain is even outside the named ranges.
3. Alaska – Approximately 268 Ranges
Alaska covers 665,000 square miles, and a large portion of that is mountainous. USGS counts approximately 268 named ranges. The headline figure is Denali (Mount McKinley) in the Alaska Range, the tallest mountain in North America at 20,310 feet (6,190 meters).
Flattop Mountain in Chugach State Park is one of the most visited peaks in the state, accessible from Anchorage. Alaska’s sheer size means many of its ranges see very few visitors.
4. Arizona – 151 Named Ranges
Arizona’s 151 USGS-named ranges put it firmly in the top five. The state is more mountainous than its desert reputation suggests. Humphreys Peak in the San Francisco Peaks is Arizona’s highest point at 12,637 feet (3,852 meters).
Coronado National Forest alone spans 17 mountain ranges. The Santa Catalina Mountains rise directly above Tucson. Explore.com’s alternate count, based on extensive map review, puts Arizona at 193 ranges with over 4,000 named individual mountains.
5. New Mexico – 131 Named Ranges
New Mexico rounds out the top five with 131 USGS-named ranges. Wheeler Peak in the Sangre de Cristo Mountains is the state’s highest summit at 13,161 feet (4,011 meters). The area around Wheeler Peak, near Taos, is a hub for skiing and outdoor activities.
Chaco Canyon National Historic Park sits surrounded by the Chuska, San Juan, and San Pedro mountain ranges. Alternate counts for New Mexico range from 88 (cited by an art museum) to 111 (Peakbagger.com) to 131 (USGS).
State-by-State Summary Table

| California | 300-plus | Mount Whitney | 14,505 ft (4,421 m) |
| Nevada | 272 | Boundary Peak | 13,140 ft (4,005 m) |
| Alaska | ~268 | Denali | 20,310 ft (6,190 m) |
| Arizona | 151 | Humphreys Peak | 12,637 ft (3,852 m) |
| New Mexico | 131 | Wheeler Peak | 13,161 ft (4,011 m) |
Which State Has the Highest Elevation Overall?
Range count and mean elevation are different measures. Colorado has the highest mean elevation of any US state at 6,800 feet (2,073 meters), despite not making the top five for named range count. Colorado holds 30 of the Rockies’ tallest peaks, including Mount Elbert at 14,440 feet (4,401 meters), the highest summit in the Rocky Mountains and the entire Mississippi River drainage basin.
Other mean elevations for context:
- Wyoming: 6,700 ft (2,040 m) – highest point Gannett Peak at 13,804 ft
- Utah: 6,100 ft (1,860 m) – highest point Kings Peak at 13,528 ft
- New Mexico: 5,700 ft (1,740 m)
- Nevada: 5,500 ft (1,680 m)
- Idaho: 5,000 ft (1,520 m) – highest point Borah Peak at 12,668 ft
- Arizona: 4,100 ft (1,250 m)
- Montana: 3,400 ft (1,040 m) – highest point Granite Peak at 12,807 ft
What Are the Mountain States?
The Mountain states are an official US Census Bureau geographic division covering eight states: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming. The region is defined by the Rocky Mountains running north-south through Montana, Idaho, Wyoming, Colorado, Utah, and New Mexico, with Arizona and Nevada adding additional ranges on the southern and western edges.
The Mountain West is the fastest-growing US region, with Utah, Idaho, Nevada, Colorado, and Arizona among the fastest-growing states. The terrain is diverse: alpine peaks, high desert, the Great Basin, the Sonoran Desert, and the Colorado Plateau all fall within the region’s boundaries. If you’re planning a trip with a partner to any of these states, it’s worth browsing romantic getaways across the United States because mountain towns do couples trips really well.
The ten highest summits in the Mountain West are all in Colorado. Notable Colorado peaks beyond Mount Elbert include:
- Mount Massive (second highest in the Rockies)
- Mount Harvard (highest in the Collegiate Peaks)
- Blanca Peak (highest in the Sangre de Cristo Mountains)
- Uncompahgre Peak (highest in the San Juan Mountains)
- Grays Peak (highest point on the Front Range and Continental Divide)
Frequently Asked Questions
What state has the most mountain ranges in the US?
California has the most named mountain ranges of any US state, with over 300 according to USGS data. Nevada is second with 272 and Alaska third with approximately 268.
Does Nevada really have more mountain ranges than Colorado?
By USGS named-range count, yes. Nevada has 272 named ranges. However, Colorado has the highest mean elevation of any US state at 6,800 feet and holds all ten of the Mountain West’s highest summits.
Which US state has the tallest mountain?
Alaska. Denali (Mount McKinley) stands at 20,310 feet (6,190 meters), making it the highest peak in both the US and all of North America. In the contiguous 48 states, California’s Mount Whitney is tallest at 14,505 feet.
What counts as a mountain range for these rankings?
The primary methodology uses the USGS geographic names database, filtering for features tagged as “range” and counting occurrences by state. Different sources use different methods, topographic maps, blog research, and government data, which is why exact numbers vary between rankings.
