Geology In

The solid iron-nickel inner core — today 1,200 kilometers (745 miles) in radius, or about three-quarters the size of the moon — is surrounded by a fluid outer core of molten iron and nickel about 2,400 kilometers (1,500 miles) thick.

Eolian sediments

 · Eolian Sediments in Alaska. Loess in Alaska is found in broad zones bordering all the major river systems ( Fig. 8 ), with the thickest and oldest deposits occurring in areas that were not glaciated, and thinner deposits, sometimes entirely of Holocene age, found in some glaciated areas.

Questions About Yellowstone Research

Heat and volcanic gases from slowly cooling magma rise and warm the dense salty water that occupies fractured rocks above the Yellowstone magma chamber. That brine, in turn, transfers its heat to overlying fresh groundwater, which is recharged by rainfall and snowmelt from the surface.

Blue hole

A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef). Their existence was first discovered in the late 20th century by fishermen and recreational divers.[1] Blue holes typically contain tidally influenced water of fresh ...

September 2018 – The Platypus Man in Yellowstone

 · The Great Sand Dunes Colorado tends to be associated with mountains, but a lot of the state is a flat plain – albeit at around 8,000 feet high, lying between mountain ranges. As we leave the National Park we drive out through just such a sagebrush plain, and can see Blanco Peak towering above us at around 14,000 feet high.

Yellowstone Cross Country Skiing

In 1881, Yellowstone Superintendent P.W. Norris, named the creek after the early explorer. This is a very popular hike in the Old Faithful area, and for good reason. It is an easygoing, short hike to one of Yellowstones major lakes and is landlocked-no roads approach it.

Yellowstone Hot Springs

 · Yellowstone National Park is composed of many different and unique geographical features which contain microbes that have adapted to the extreme conditions. The hot springs contain thermophiles that have managed to thrive in extreme temperatures that other organisms could not survive in and have developed specialized methods of metabolism to adapt to these extreme environments.


 · Fossil of plants, invertebrates, vertebrates, and trace fossils have been identified in Yellowstone National Park from more than 40 stratigraphic units (rock layers of known age and origin) spanning more than 540 million years from the Cambrian to the Cenozoic eras. Paleontological resources, or fossils, are any remains of past life preserved ...

Great Sand Dunes NP – The Platypus Man in Yellowstone

 · The Great Sand Dunes. Colorado tends to be associated with mountains, but a lot of the state is a flat plain – albeit at around 8,000 feet high, lying between mountain ranges. As we leave the National Park we drive out through just such a sagebrush plain, and can see Blanco Peak towering above us at around 14,000 feet high.

Hydrothermal Features

 · Yellowstone National Park preserves the most extraordinary collection of hot springs, geysers, mudpots, and fumaroles on Earth. More than 10,000 hydrothermal features are found here, of which more than 500 are geysers. Microorganisms called thermophiles, or heat lovers, make their homes in the hydrothermal features of Yellowstone.


When erosion takes place, sedimentation— the deposition of material—also eventually occurs. Through time, sediments are buried by more sediments and the material hardens into rock. This rock is eventually exposed (through erosion, uplift, and/or faulting), and the cycle repeats itself.

Types and classifications of springs

 · At Sand, Box Canyon, and Blind Canyon Springs the water … comes from a stratum consisting largely of white sand which is overlain by a thick sheet of lava. At most of the springs there is so much talus that the true source of the water cannot be observed, but it probably issues chiefly from the large openings in scoriaceous or shattered basalt where the basalt overlies more dense rocks.


 · To monitor volcanic and seismic activity in the Yellowstone area the Yellowstone Volcano Observatory (YVO) was established in 2001. YVO is partnership of scientists from the US Geological Survey, National Park Service, University of Utah, University of Wyoming, University NAVSTAR Consortium (UNAVCO) and the state Geological Surveys of Wyoming, Montana and Idaho.

Ross''s Bentgrass

 · Ross''s bentgrass is native to the geyser basins along the Firehole River. NPS. Yellowstone''s geothermally influenced plant communities contain species that must be able to tolerate a wide range of conditions. Although most of these species are widespread in range and occur at diverse elevations, not all of them are common.

Dreaming of Yellowstone

We were dreaming of Yellowstone but ended up finding so much more. Our route would take in Utah, Wyoming, Montana, and Idaho, covering paved and dirt roads, small tracks, and sand – all the while surrounded by stunning scenery. So, in late September, we left Copenhagen, Denmark for Salt Lake City in the north of Utah, dreaming of Yellowstone.

Yellowstone National Park

The Yellowstone sand verbena is a rare flowering plant found only in Yellowstone. It is closely related to species usually found in much warmer climates, making the sand verbena an enigma. The estimated 8,000 examples of this rare flowering plant all make their home in the sandy soils on the shores of Yellowstone Lake, well above the waterline.

Email: Yellowstone Push – Thrill of the Chase

Yellowstone National Park, Resources and Issues, Vegetation

The Yellowstone sand verbena grows close to the sand surface and rarely rises more than three inches from the surface of the sand. Some individuals occur near warm ground, so the thermal activity in Yellowstone may be helping this species survive. The


 · Yellowstone''s northern range has been the focus of debate since the 1930s. Cycles and processes are essential connections within an ecosystem.
