Newberry National Volcanic Monument was designated on November 5, 1990, to protect the area around the Newberry Volcano in the U.S. state of Oregon. The monument was created within the boundaries of the Deschutes National Forest, which is managed by the U.S. Forest Service, and includes 54,822 acres of lakes, lava flows, and geologic features in central Oregon.
Newberry Volcano is a large, active, shield-shaped stratovolcano located about 20 miles (32 km) south of Bend, Oregon, United States, 35 miles (56 km) east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. Newberry is the largest volcano in the Cascade Volcanic Arc, with an area of 1,200 square miles (3,100 km2) when its lava flows are taken into account. From north to south, the volcano has a length of 75 miles (121 km), with a width of 27 miles (43 km) and a total volume of approximately 120 cubic miles (500 km3). It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855.
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave.
Sunset Crater is a cinder cone located north of Flagstaff in the U.S. state of Arizona. The crater is within the Sunset Crater Volcano National Monument.
El Malpais National Monument is a National Monument located in western New Mexico, in the Southwestern United States. The name El Malpais is from the Spanish term Malpaís, meaning badlands, due to the extremely barren and dramatic volcanic field that covers much of the park's area.
Cueva de los Verdes is a lava tube and tourist attraction of the Haria municipality on the island of Lanzarote in the Canary Islands (Spain). The cave lies within the Monumento Natural del Malpaís de La Corona, a protected area of the Canary Islands.
Lava Butte is a cinder cone in central Oregon, United States, just west of U.S. Route 97 between the towns of Bend, and Sunriver in Deschutes County. It is part of a system of small cinder cones on the northwest flank of Newberry Volcano, a massive shield volcano which rises to the southeast. The cinder cone is capped by a crater which extends about 60 feet (20 m) deep beneath its south rim, and 160 feet (50 m) deep from the 5,020-foot (1,530 m) summit on its north side. Lava Butte is part of the Newberry National Volcanic Monument.
The Deschutes National Forest is a United States national forest (NF) located in Central Oregon, in parts of Deschutes, Klamath, Lake, and Jefferson counties. It was established in 1908, with border changes following in 1911 and 1915. The forest now encompasses almost 1.6 million acres (6,500 km2) along the east side of the Cascade Range. The forest is bordered to the south by the Fremont–Winema NF, to the southwest by the Umpqua NF, and to the west by the Willamette NF.
Zuni-Bandera volcanic field is a volcanic field located in the state of New Mexico, United States.
Malpaís, in the Southwestern United States, Spain, Mexico, and other Spanish-speaking regions, are rough and barren landscapes that consist of relict and largely uneroded lava fields exhibiting recognizable lava flows, volcanic cones, and other volcanic landforms. This type of volcanic landscape is extremely rough and difficult to traverse. It is characteristic of arid environments because in more humid climates, such rough terrains are smoothed by erosion and vegetation.
A lava cave is any cave formed in volcanic rock, though it typically means caves formed by volcanic processes, which are more properly termed volcanic caves. Sea caves, and other sorts of erosional and crevice caves, may be formed in volcanic rocks, but through non-volcanic processes and usually long after the volcanic rock was emplaced.
The Lava River Cave near Bend, Oregon, is part of the Newberry National Volcanic Monument, which is managed by the United States Forest Service. At 5,211 feet (1,588 m) in length, the northwest section of the cave is the longest continuous lava tube in Oregon. While the cave's discovery in 1889 was officially credited to a pioneer hunter, the presence of obsidian flakes near the cave has led archaeologists to conclude that Native Americans knew about the cave long before settlers arrived in central Oregon.
Surtshellir is a lava cave located in western Iceland, around 60 km from the settlement of Borgarnes. Approximately a mile in length, it is one of the longest such caves in the country. It was the first known lava tube in the world, at least by modern speleologists, and remained the longest known lava tube until the end of the 19th century. While mentioned in the medieval historical-geographical work Landnámabók, Eggert Ólafsson was the first to give a thorough documentation of the cave in his 1750 travels of the region. It is named after the fire giant Surtr, a prominent figure in Norse mythology, who is prophesied to one day engulf the world in the fire of his flaming sword.
Gruta das Agulhas is a cave located along the promontory of Ponta dos Coelhos, in the Bay of Refugo, in the civil parish of Porto Judeu, in the municipality of Angra do Heroísmo, the Portuguese archipelago of the Azores.
Gruta das Torres, is a lava cave, a geological formation of volcanic origin formed from the flow and cooling of subterranean magma rivers. This formation is located outside the parish of Criação Velha, in the municipality of Madalena, on the western flanks of the island of Pico. The cave system formed from a series of pāhoehoe lava flows which originating from the Cabeço Bravo parasitic cone about 500 to 1500 years ago. The caves are a group of interconnected lava tubes between 0.5–22 metres (2–72 ft) width, created from both pāhoehoe and ʻaʻā types of lavas generated during different geological periods. It has a height between 1.1 and 15 metres (3.6–49 ft) and is located at an elevation of 300 metres (980 ft). With an estimated length of over 5.2 km (3.2 mi) it is the longest lava cave in the Azores. Access to the cave was managed by the Mountaineering Association. Starting in 2011, AZORINA, SA took over the management and organization of the cave.
Manjanggul (Korean: 만장굴) is a lava tube located in Gimnyeong-ri, Gujwaeup, Jeju City, South Korea. At up to 23 metres (75') wide, 30 metres (100') high and 8.928 km long, it is the 12th-longest lava tube in the world and the second longest on Jeju Island, although a significant portion of the cave is closed to visitors. It is the only cave of the Geomunoreum Lava Tube System, considered one of the finest lava tube systems in the world, regularly open to the public. It is also part of the UNESCO World Heritage Site list, under the item Jeju Volcanic Island and Lava Tubes.
The Azores Geopark is a network of 121 geographically-dispersed sites of geographic heritage and marine areas that covers the nine volcanic islands of the archipelago of the Azores. This network is managed by the Azores Geopark Association, a non-profit association, with its headquarters in Horta on the island of Faial, established 19 May 2010. It is part of the European Geoparks Network and the UNESCO Global Geoparks Network. The Association's mission is to ensure the geological conservation, environmental education and sustainable development, while promoting the well-being of the population and a respect for the environment.
Bandera Volcano Ice Cave, also known as Zuni Ice Cave, is a lava tube cave in New Mexico with an internal temperature significantly less than above-ground summertime ambient temperature; it contains perennial ice. The inside temperatures can fluctuate between −1 and 10 °C. Some areas of the ice cave never reach above freezing. For years, local Indigenous people used the cave to store food.
