Valles Caldera

https://www.nps.gov/vall/index.htm https://en.wikipedia.org/wiki/Valles_Caldera_National_Preserve The Valles Caldera National Preserve is located in northeastern Sandoval County and southern Rio Arriba County, just west of Los Alamos. It protects a large portion of the Valles Caldera, an area of significant geological, ecological and cultural interest. About 1.25 million years ago, a spectacular volcanic eruption created the 13-mile wide circular depression now known as the Valles Caldera. The preserve is known for its huge mountain meadows, abundant wildlife, and meandering streams. The area also preserves the homeland of ancestral native peoples and embraces a rich ranching history.

Crater Lakes Water lakes may exist in craters and calderas (large collapse features) as these depressions can become filled by rainwater or melting snow or ice, or be places where groundwater can accumulate at the surface. Crater lakes can be long-lived or ephemeral, and may contain fresh or acidic waters. crater lake and snowy rim An Endangered Amphibian on an Active Volcano:  the Jemez Mountains Salamander at Valles Caldera Valles Caldera National Preserve is a very important place for the Jemez Mountains salamander. The preserve is one of the largest, fully protected areas throughout the species’ historical range. The Natural Resource Condition Assessment Program recently partnered with Utah State University to determine what we know about the salamander in the preserve and how it is doing. Find out more about this secretive creature and what we learned. brown salamander in vegetation debris Fumaroles Fumaroles are places where steam and volcanic gases are emitted. They are present on most active volcanoes. The occurrence of fumaroles and other geothermal features such as hot springs, geysers, and mud pots are important signs that a volcano is active. steam vents on the crater rim Ultra-Plinian Eruptions These caldera-forming eruptions are the largest of all volcanic eruptions. These eruptions have higher eruption rates that form higher eruption columns and produce widespread pyroclastic flows. View overlooking extensive flat ground covered with trees and meadows Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios. Green, orange, and dead grey junipers in red soil, mountains in background Volcanic Domes Lava domes are steep-sided rounded accumulations of highly viscous silicic lava over a vent. Some domes are part of composite volcanoes, but large ones can make up their own volcanoes. Lassen Peak is a dome. photo of a rounded hill of blocky rock Life on Redondo Peak: Plant and Arthropod Diversity at Valles Caldera’s Highest Elevations Valles Caldera National Preserve: Redondo Peak is the highest point in the preserve (11,260 feet in elevation). A comprehensive inventory of plants and animals was conducted there in 2014. A recent condition assessment for the preserve focused on inventory results for plants and arthropods, and, among other things, found 101 plant species on Redondo Peak (98 of them native), 60 moth species (including four newly recorded for the park), and at least 75 species of spiders.

A recent Natural Resource Condition Assessment evaluated seven resources at the preserve: landscape connectivity, visual resources (or scenic views), Redondo Peak diversity, wetlands, New Mexico meadow jumping mouse habitat, the Jemez Mountains salamander, and songbirds. Dark sky with stars reflected in a wetland pond What’s furry, has big back feet, and lives by a stream? Answer: The New Mexico Meadow Jumping Mouse! Valles Caldera National Preserve: One of 22 known populations (in New Mexico) of the endangered New Mexico meadow jumping mouse lives in stream-side wetlands in Valles Caldera National Preserve. As part of a recent study, the NPS and its partners summarized the occurrence of the mouse in the park and surrounding area, identified potential jumping mouse habitat in the park, and identified two indicators of habitat condition that could be used for a future condition assessment.

Songbirds at Valles Caldera National Preserve Valles Caldera National Preserve: Do you have a favorite songbird species that visits your feeder or nests in your yard or local park? With its variety of habitats, Valles Caldera has nearly 200 species of birds on its checklist, with 117 species known or suspected to breed there. A recent condition assessment at the preserve used existing data to assess songbird species richness and abundance, and to see if key indicator species of each habitat type were present.

Restoring Wetlands at Valles Caldera Valles Caldera National Preserve: Wetlands are some of the most valuable ecosystems on Earth. Among their many values are providing fish and wildlife habitat, improving water quality, and easing damage from floods and storms. As in many other places, wetlands in Valles Caldera have been impacted by human activities of the past. However, wetlands in the preserve are being restored, and according to a recent condition assessment, restoration efforts are working.

Pine forest with snow. Series: Volcanic Features Volcanoes vary greatly in size and shape. Volcanoes also may have a variety of other features, which in turn, have a great range in diversity of form, size, shape, and permanence. Many volcanoes have craters at their summits and/or at the location of other vents. Some craters contain water lakes. Lakes of molten or solidified lava may exist on some volcanoes. Fumaroles and other geothermal features are a product of heat from magma reservoirs and volcanic gases. photo of a lava lake in a summit crater How Connected is the Landscape at Valles Caldera? Valles Caldera National Preserve: Connected, intact landscapes are vital for movements and survival of animal and plant populations. A loss of connectivity, such as from highways and other human developments, can effectively reduce the size and quality of available habitats and disrupt needed movements. The Natural Resource Condition Assessment Program and its partners evaluated the condition of landscape connectivity at the preserve. Find out what we learned. Scenic view across the caldera including dark green spruce, yellow aspen, and brown grassland Series: Volcano Types Volcanoes vary in size from small cinder cones that stand only a few hundred feet tall to the most massive mountains on earth. photo of a volcanic mountain with snow and ice Calderas Calderas are large collapse features that can be many miles in diameter. They form during especially large eruptions when the magma chamber is partially emptied, and the ground above it collapses into the momentary void. Crater Lake and Aniakchak Crater are calderas. photo of oblique aerial view of a volcanic caldera with snow and ice Explosive Calderas Explosive calderas result from violent eruptions of great quantities of silicic magmas. These eruptions produce massive eruption columns that extend into the stratosphere, and voluminous pyroclastic flows. Eruptions that produce explosive calderas generally range from 6 (Colossal) on the Volcanic Explosivity Index (VEI) to 8 super eruptions (Apocalyptic). digital oblique aerial image of a volcanic caldera Resurgent Calderas Resurgent calderas are substantially larger than summit calderas with diameters of many tens of miles (kms). Although they form in areas that have previously experienced volcanism, they do not form on any preexisting volcanic edifice. VEI 7-8 eruptions lead to caldera formation. a shaded relief of a volcanic caldera with rim outlined, and domes and cones colored Series: Volcanic Eruption Styles Categories in this traditional classification are based on the eruption styles of particular volcanoes. These magmatic eruption styles are listed in the order of increasing explosivity. volcanic eruption with glowing lava Pyroclastic Flows and Ignimbrites, and Pyroclastic Surges Pyroclastic flows and surges are among the most awesome and most destructive of all volcanic phenomena. Pyroclastic flow deposits are found in at least 21 units of the National Park System. photo of a cloud of ash and dust moving down a mountain side. Volcanic Ash, Tephra Fall, and Fallout Deposits Volcanic ash, pumice, and tephra ejected in volcanic eruptions ultimately falls back to Earth where it covers the ground. These deposits may be the thin dustings or may be many tens of feet (meters) thick near an eruptive vent. Volcanic ash and tephra can present geohazards that are present great distances from the erupting volcano. photo of a bluff with exposed fine-grained volcanic ash and pumice.
