Introduction

The National Park System contains a majority of the most significant volcanoes in the United States. National parks include

Two of the most perfect cinder cones in North America (Capulin Volcano and Sunset Crater Volcano national monuments),
The site of the largest eruption in the 20th century (Katmai National Park),
The example for resurgent calderas (Valles National Preserve),
The greatest concentration of geysers on Earth (Yellowstone National Park),
The best example of columnar jointing on the continent (Devils Postpile National Monument),
At least 20 volcanoes that are active or potentially active, including Mauna Loa and Kīlauea in Hawaii Volcanoes National Park, Iliamna and Redoubt in Lake Clark National Park, and Lassen Peak in Lassen Volcanic National Park which erupted in 1914-1917.

Nineteen national park sites were set aside primarily for their volcanic resources. These parks have volcanic resources identified as a park significance, listed as a fundamental resource or value, or specifically called-out in their enabling legislation.

Aniakchak National Monument, Alaska

Aniakchak caldera is one of the best exposed calderas on the planet. It is located on the Aleutian Peninsula in Alaska and is one of the least visited units in the National Park System. The Aniakchak caldera formed 3,660 ± 70 years ago during a Volcanic Explosivity Index (VEI) 6 (Colossal) eruption that was one of the largest eruptions of the Holocene. The caldera has a diameter of about 6.6 miles (10.5 km) and is about 2,000 feet (610 m) deep. Post-caldera eruptions have formed a series of domes, cones, maars, and lava flows within the caldera, with the most recent eruption occurring in 1931.

Capulin Volcano is one of the tallest and most perfectly formed cinder cones in North America standing nearly 1,300 ft (400 m) above the surrounding plain in northeastern New Mexico. Capulin Volcano erupted about 54,200 ± 1,800 years ago forming the cinder cone, and erupting a series of lava flows from vents along its base. Capulin Volcano is located near the center of the Raton-Clayton Volcanic Field, the easternmost young volcanic field in the United States which experienced intermittent activity over the last 9 million years.

Crater Lake is a summit caldera with a diameter of 5-6 miles (8-10 km) that formed in a Mega-colossal (VEI 7) eruption 7,700 years ago that culminated in caldera collapse. The eruption had an estimated volume of 12 cubic miles (50 cubic km) making it the largest prehistoric eruption in the contiguous United States. Crater Lake is the deepest lake in the United States, with the primary source of water in the lake being precipitation. It took approximately 460 years to fill. The park was established in 1902 and was the third national park set aside for its volcanic resources.

Craters of the Moon National Monument, Idaho

Craters of the Moon is one of the best areas in the contiguous United States to explore a monogenetic volcanic field that has experienced abundant Holocene volcanism. Activity in the field began about 15,000 years ago with the most recent eruption occurring about 2,100 years ago. The field contains the Craters of the Moon, Wapi, and Kings Bowl lava fields along the Great Rift volcanic rift zone on the Snake River Plain.

Devils Postpile National Monument contains one of the most spectacular examples of columnar jointing in the United States. The postpile consists of columns that are up to 60 ft (18 m) long and have a diameter up to 2.5 ft (1.1 m). Columnar jointing forms during rapid cooling of lava flows and other igneous bodies due to fracturing caused by contraction. Devils Postpile is in a basalt lava flow that erupted about 100,000 years ago.

Devils Tower National Monument, Wyoming

Devils Tower National Monument has the distinction of being the first national monument established under the authority of the Antiquities Act in 1906. Devils Tower stands about 867 feet (265 m) tall, but its origin is not completely understood. It may be a volcanic neck, a remnant of a maar-diatreme volcano, or result from erosion of a shallow intrusion. Spectacularly-developed columnar jointing is one of the tower’s most distinctive features.

El Malpais National Monument preserves part of the Zuni-Bandera Volcanic Field, which is notable for its lava flows of unusually large length and large volume, and for its diversity of vent types and lava flow morphologies. The Zuni-Bandera Volcanic Field is located along the southern boundary of the Colorado Plateau in New Mexico and experienced three phases of activity in the last 700,000 years. The most recent eruption produced the McCartys Flow 3,900 years ago. El Malpais contains several cinder cones, one of the longest lava tube systems in the world, and the southernmost ice caves in North America. Research on the McCartys Flow has been important for understanding the emplacement of lava flows by inflation, providing new insights into the formation of basaltic lava flows on Earth, the Moon, and Mars.

Haleakalā Volcano, otherwise known as East Maui volcano, is on the island of Maui, the second youngest island in the Hawaiian chain. It is the only Hawaiian volcano not located on the Big Island that is potentially active today. Its most recent eruption occurred about 400 years ago. The volcano began erupting about 2 million years ago, and about 97% of its volume is below sea level. Haleakalā Crater in the summit region is actually an erosional feature. The volcano is in the post-shield phase with a lower magma production rate. Several young cinder cones are located near the summit and along the flanks of the volcano.

Hawai’i Volcanoes National Park contains parts of Mauna Loa and Kīlauea, two of the most active shield volcanoes on Earth. Mauna Loa is the largest active volcano on the planet. From its base on the sea floor, Mauna Loa is almost 33,500 feet (10,211 m) tall.

With the exception of a quiet period between 1924 and 1952, Kīlauea mostly has been in eruption since 1780 CE (e.g., since reliable written record-keeping began). Eruptions have occurred from both the rift zones and the summit caldera. Shield volcanoes have numerous summit calderas during their lifespans. Kīlauea’s current summit caldera has been in existence for about the last 500 years and has intermittently hosted a lava lake in the Halemaʻumaʻu pit crater. The Kīlauea caldera recently underwent further collapse in 2018 when an eruption along the lower East Rift Zone partially drained the summit magma chamber.

Katmai NP is within one of the most active volcanic areas on Earth as it sits along the Pacific Ring of Fire. The park contains 14 volcanoes that have had historic or prehistoric activity. Ten of these volcanoes are considered active by the USGS Alaska Volcano Observatory.

The 1912 Valley of Ten Thousand Smokes eruption was the largest of the 20th Century. This VEI 6 (Colossal) eruption from Novarupta, a vent about 6 mi (10 km) from Mount Katmai, lasted for about 60 hours and drained the magma reservoir underneath Katmai leading to caldera collapse. The eruption left a thick ignimbrite in the Valley of Ten Thousand Smokes, so named for the vigorous fumaroles that persisted for decades after its emplacement. Ash from the eruption rose to 19 mi (30 km) into the stratosphere and produced thick ash deposits formed throughout much of southern Alaska. The Novarupta vent was plugged with a lava dome at the end of the eruption.

The most recent volcanic activity in Katmai NP includes eruptions at Trident Volcano (1954-1973) and Fourpeaked (2006).

Lake Clark National Park contains two active composite volcanoes, Iliamna and Redoubt, which are both also National Natural Landmarks. Redoubt has experienced several eruptions since 1900, most recently in 1989-1990 and again in 2009. These eruptions reached a maximum 3 (Catastrophic) on the Volcanic Explosivity Index (VEI) and sent ash clouds to an elevation as high as 62,000 feet (19 km), and formed lava domes, ash-flows, and lahars. Iliamna is considered active, although reports of historic activity are not definitive. Both volcanoes also have active fumaroles.

Lassen Volcanic National Park is home to four different types of volcanoes (dome, composite volcano, cinder cone, and shield volcano). Two of the most recent eruptions in the contiguous United States took place within the park boundary, with Lassen Peak erupting between 1914 and 1917 and Cinder Cone erupting in approximately 1666 CE (Common Era).

Lassen Peak is considered to be the world’s largest dome with a peak elevation of 10,457 feet (3,187 m) and was emplaced about 27,000 years ago. Lassen Peak’s eruptive activity in 1915 included directed blasts that blew out a crater at the summit, sent an eruption column 30,000 feet (9,000 m) into the atmosphere, and generated pyroclastic flows and lahars. The park also has several active hydrothermal areas.

Lava Beds NM contains a number of lava flows that were erupted from fissures on the flank of Medicine Lake Volcano in northern California, a large shield which is mostly outside of the monument. Medicine Lake Volcano, the largest volcano by volume in the Cascade Range, has been active since about 500,000 years ago. The park contains fissure volcanoes, cinder cones, and spatter cones. Lava Beds NM also protects the largest concentration of lava tube caves in North America and contains more than 700 lava tube caves.

Mount Rainier is the tallest volcano in the Cascades with an elevation of 14,410 ft (4,392 m). The most recent magmatic eruption at this composite volcano occurred approximately 1,000 years ago, and reports of historic eruptions are not considered reliable. Mount Rainier is considered to be the most dangerous volcano in the continental United States because of its propensity for unleashing catastrophic lahars and its proximity to densely populated areas. Mount Rainier is heavily glaciated, and the presence of ice, snow, and abundant surface water, along with the prevalence of weak hydrothermally-altered rock on the volcano’s slopes, make Mount Rainier especially susceptible to lahars. The Osceola Mudflow travelled all the way to Puget Sound 5,600 years ago area and left lahar deposits covering approximately 212 square miles (550 square kilometers).

Pinnacles National Park contains the deeply-eroded remnants of a volcanic center or field that erupted approximately 23 million years ago. The park is located along the San Andreas Fault, and movement along the fault has moved the western portion of this ancient volcano approximately 200 miles (320 km) north relative to its eastern part. Rocks exposed in the park include volcanic breccias, lava flows, and tuffs. The park’s namesake pinnacles result from erosion along vertical joint systems.

Sunset Crater is the youngest volcano in the San Francisco Volcanic Field in northern Arizona, erupting in 1085 CE (common era). The volcano was named for the oxidized red cinders along its rim. Sunset Crater’s eruption was especially vigorous for a cinder cone, being Sub-Plinian with a VEI of 4. It was propelled by unusually high concentrations of CO2 in the magma. The eruption column reached an estimated elevation of 65,000 ft (20 km), and tephra deposits from the eruption covered an area of almost 200 square miles (500 square km). The eruption greatly impacted the ancestral Puebloan people living in the region.

Valles Caldera, a resurgent caldera located in the Jemez Mountains of north-central New Mexico, formed 1.24 million years ago. The Valles Caldera is nearly 14-mi (22 km) in diameter, and its resurgent dome, Redondo Peak, is approximately 3,300 ft (1,000 m) higher than the caldera floor. A previous caldera-forming eruption took place 1.6 million years ago just to the northeast of Valles Caldera. Both eruptions produced voluminous air-fall and ash-flow tuffs including the Bandelier Tuff exposed in Frijoles Canyon in Bandelier National Monument. Valles Caldera is the type example for resurgent calderas, and is one of the best studied examples of this type of volcanic center.

Volcanism has occurred in the Yellowstone region over the last 50 million years. During the last 2.1 million years, Yellowstone was the site of three large caldera-forming eruptions. The first of these eruptions was the largest. The eruption of the Huckleberry Ridge Tuff coincided with the formation of a resurgent caldera 53 by 28 miles (85 by 50 km) in diameter and the eruptive volume of 590 cubic miles (2,450 cubic km), making it one of the largest eruptions in geologic history. The most recent caldera-forming eruption occurred 640,000 years ago. The Yellowstone region is underlain by a mantle plume.

Post-caldera volcanisms has produced large volume rhyolitic lava flows, with the most recent eruption occurring about 70,000 years ago.

Yellowstone is also one of the planet’s most impressive geothermal areas and includes the greatest concentration of geysers on the planet. The park contains more than 10,000 hydrothermal features, including approximately 500 geysers and approximately 2,000 fumaroles, as well as mud pots and hot springs.

Excerpts Related to Volcanic and Geologic Resources

Aniakchak NM -- 16 U.S.C. 410hh(1)

-- 1978

-- “The Aniakchak Caldera is located in the heart of the Aloaska Peninsula. It is so unexpected a feature that it remained unknown to all but the Natives of the region until

about 1920. With its average diameter of approximately six miles, Aniakchak is one of the world’s largest calderas.

In the interior of the caldera are textbook examples of certain volcanic features such as lava flows, cinder cones, and explosion pits. Also lying within the caldera is Surprise Lake which is fed by warm springs and is uniquely charged with chemicals. Surprise Lake is the source of the Aniakchak River, which cascades through a 1,500 foot gash in the caldera wall and downward 27 miles to the Pacific Ocean.

The flanks of the caldera provide a geological and biological continuum by which to make a comparative study of the formation of the caldera and the significant process of biological succession of both plant and animal species occurring in the vicinity of the caldera, an area that was rendered virtually devoid of life forms by a major eruption of the volcano in 1931….

The land withdrawn and reserved by this Proclamation [is] for the protection of the geological, biological, climatological and other phenomena…

NOW, THEREFORE, I, JIMMY CARTER … set apart … the Aniakchak National Monument…” 93 Stat 1448-49 (1978).

“Lava Beds National Monument covers 72 square miles within Siskiyou and Modoc counties in northeastern California. The Monument is the site of the largest concentration of lava tube caves in the United States. The monument lies on the northeast flank of the Medicine Lake shield volcano, the largest volcano in the Cascade Range. The region in and around the monument is unique because is lies on the junction of the Sierra-Klamath, Cascade, and Great Basin geological provinces. In addition, the monument is geologically outstanding because of its great variety of ""textbook"" volcanic formations; i.e., lava tube caves, fumaroles, cinder cones, spatter cones, maar volcanoes, and lava flows. Over 30 separate lava flows located in the park range in age from 2,000,000 years BP to 1,110 years BP. Some of the major Lava Flows within Lava Beds National Monument include: Callahan Flow, Schonchin Flow, Mammoth Crater Flow, Modoc Crater Flow, and Devils Homestead Flow. In addition to these surface geologic resources , the monument has a significant and popular underground resource. Presently over 460 lava tube caves and features have been identified in the monument. The field inventory process for cave resources is not yet complete. These caves are notable in their abundance, length of passage, and excellent preservation of primary volcanic features; several also contain specific features of interest such as pictographs, ice formations, and biological resources of scientific interest.” Source: http://www.nps.gov/labe/pphtml/naturalfeatures.html
