25 Stunning Volcanoes Spread Across the United States

Edited By: Violet Tar

 Volcanoes are essentially ruptures in the surface of the Earth that cause lava, heat and resultant ash and gas to escape from magma chambers within the Earth’s core. North America is home to over 250 volcanoes, more than half of which are spread across the United States of America. 

These eruptions can create some truly breathtaking physical formations, many of which are still active, some which have even recently erupted, and others which have remained dormant for millions of years. They are home to a variety of unique ecosystems and wildlife, and many are even the ultimate vacation spots depending on whether you're looking for a picturesque view or an adventure

Here are 25 volcanoes you can find across various states in America, many of which make excellent destinations for trekking, and a few of which are best enjoyed through these photographs.  

    

1. Mount Akutan, Alaska

This volcano is one among many in Alaska and has a 2 km caldera (which are the craters that form after a volcanic eruption after the magma chambers have emptied completely). This crater was caused by a massive explosion that occurred nearly 2000 years ago.

It has since experienced lava flows and eruptions as recently as 1992. It continues to experience periodic steam and gas emissions. Its highest peak stands at 4,275 feet.


2. Amak Volcano, Alaska

Here is another volcano that is a part of the Aleutian Islands, found more specifically on Amak Island. It has an elevation of 1600 feet and is the source of many unique minerals and elements. It last erupted in 1796, which created the crater that is currently there.

Amak Island is uninhabitable but can be visited after receiving permission from the United States Fish and Wildlife Service. As planes are not allowed on Amak Island, the island can be reached by boat from Cold Bay, the nearest city.       


3. Mount Aniakchak, Alaska

Mount Aniakchak was formed a little under 4000 years ago, and is now in a protected area called Aniakchak National Monument and Preserve. The initial eruption that caused the largest craters of this volcano occurred approximately 2000 years ago. However, the most recent eruption recorded occurred in 1931, which caused further minor craters to form.

Within these craters is Surprise Lake, the source of Aniakchak River. In 1967, this natural wonder was designated by the National Park Service a National Natural Landmark.   

 

4. Bogoslof Island, Alaska

This island is home to a stratovolcano, the majority of which is located under the seabed and below the island. The volcano itself stands at 6000 feet, but it is only the summit that is found on the island and has an elevation of a little under 500 feet.

Most of the island is believed to have been formed more recently, after a series of eruptions in the early 20th century, though the initial land formation occurred due to underwater eruptions in 1796. It has also been declared a National Natural Landmark, and in 1909, was declared a sanctuary for nesting marine birds and sea lions, by President Theodore Roosevelt.

     

5. Devils Desk, Alaska

Devils Desk is a stratovolcano that stands approximately 5800 feet above sea level. However, the peak of the summit stands at an estimated 6400 feet. This volcano is believed to have been formed approximately 250,000 years ago, but the date has not been conclusively determined.

The edifice of this mountain is solely the neck of what used to be a much larger volcano that was severely affected by glacial erosion, creating the Devils Desk that is there today.  


6. Fourpeaked, Alaska

Fourpeaked is an active volcano found in the Fourpeaked Glacier of Alaska, that is carefully watched by the Alaska Volcano Observatory. After 10,000 years of dormancy, in September 2006, Fourpeaked experienced a series of fumaroles, fissures in the mountain from which volcanic gases are released (as seen in the photograph). 

This seismic activity was eventually classified as an explosive eruption and resulted in further smaller explosions that continued until March 2007. The classification of the volcanic activity at Fourpeaked has since been lowered to normal.   

 

7. Mauna Loa, Hawaii

Mauna Loa is one of the 5 volcanoes forming the island of Hawaii and is one of the largest volcanoes in the world in both volume and mass. It is one of the few active volcanoes present in the world and has been erupting for over 700,000 years, and since a final rumble in 1984, has largely returned to dormancy.  

These eruptions are largely non-explosive and involve multiple lava flows, which caused the summit to rise above the seabed around 400,000 years ago. 

For the experienced hiker, there are trails that have been built through the Hawaii Volcanoes National Park, where Mauna Lao is located.   


8. Kilauea, Hawaii

This is the most active of the 5 major volcanoes of Hawaii and has been continuously erupting from the early 1980s to as recently as 2018. The eruption in 2018 caused much destruction to the nearby towns of Kapoho and Vacationland Hawaii.

Access to the mountain for tourists, which has been open since as early as 1840, was briefly restricted but has since been reopened. Numerous hiking trails and guided ranger tours are available, and in the neighboring town of Kalapana, a Lava Viewing Area has been opened.    

 

9. Lassen Peak, California

This peak stands high above Sacramento Valley, with an elevation of approximately 10,400 feet. It is located in Lassen Volcanic National Park, a 100,000-acre space dedicated to preserving, observing and studying the areas most affected by eruptions. 

This research is ongoing as the volcano is still active, and continues to create minor lava flows and induce mudslides. However, the surrounding area along with nearby Lassen National Forest, are popular destinations for numerous fun activities like backpacking, hiking, kayaking, and skiing.     

 

10. Taum Sauk Caldera

This volcano is older than imaginable and last erupted nearly 1 and a half billion years ago. It is the highest mountain in Missouri, with a relatively low elevation level of approximately 1500 feet.

Due to the long dormancy period, the area surrounding this dormant volcano became the Taum Sauk Mountain State Park. This park, along with neighboring parks like Bell Mountain Wilderness Area, are excellent destinations for campers and hikers. 

 

11. Capulin Volcano National Monument

Mount Taylor is another dead volcano, that experienced its last eruption over one and a half million years ago. 
It is the highest point of Cibola National Forest, in New Mexico, and was named after President Zachary Taylor in 1849.

Mount Taylor also happens to be the location of an annual endurance event called the Mount Taylor Winter Quadrathlon, which includes 43 miles of running, cross country skiing, bicycling and snowshoeing. Other activities include hiking, trekking, and a 31-mile run.    

 

13. Shiprock, New Mexico

This rock is governed by the Navajo Nation, and with a name that means “winged rock”, this formation has played a significant role in Navajo history an culture. It is a monadnock formed from volcanic breccia, a result of a volcanic eruption that occurred over 27 million years ago.

As the formation is in a Navajo Religious site, and due to falls and injuries that occurred while hiking Shiprock in the past, this rock has been cordoned off from public access.   

 

14. Sierra Blanca, New Mexico

The Farallon de Pajaros is one of 14 islands located in the Commonwealth of the Northern Mariana Islands and is the northernmost island. It is the top of an active stratovolcano and is intertwined with two other submerged volcanoes. These volcanoes have been associated with eruptions in 1979 and 2001.

It was previously inhabited but since 1985, has been designated a protected wilderness area to conserve natural resources. Since 2009, it has been designated a part of the United States Marianas Trench Marine National Monument  


16. Alamagan, Commonwealth of the Northern Mariana Islands (CNMI)

Alamagan stretches across 4.8 km and has a peak that stands at 13,000 feet. Eruptions are believed to have occurred on this island from as early as 1500 years ago, to as recently as 1887.

The eruptions have since ceased, though there is still some fumaric activity detected on the island from time to time. The island was scarcely populated over the last century but according to a 2010 consensus, is now completely uninhabited.  


17. Anatahan, Commonwealth of the Northern Mariana Islands (CNMI)

This island is home to the most active of the volcanoes in the archipelago of the Mariana Islands. It was infrequently populated through the 20th century, but all inhabitants were evacuated due to earthquakes and fumarole gas emissions that were believed to be signs of an impending eruption that never occurred.

In 1992, a similar scare occurred, but the first true eruption occurred in May 2003, which led to the formation of a new crater in the eastern part of the island. The last eruption began in 2007 and lasted an entire year. 


18. Pagan (island), Commonwealth of the Northern Mariana Islands (CNMI)

This volcanic island is located approximately 2 miles from the main island of the Northern Mariana Islands. Pagan is a stretch of land consisting of 2 volcanoes, connected by a narrow ridge. The southern volcano was last active in 1864, while the northern volcano has experienced eruptions periodically from 1820 until 1985, with further outbursts occurring as recently as in 2012.

When a more severe eruption occurred in 1981, the island’s 300 residents were evacuated to Saipan, the main island, and efforts are still being made to restore these inhabitants to their homeland.  

 

19. Mount Bachelor, Oregon
