Beatty, Nevada
Beatty ( ) is an unincorporated town along the Amargosa River in Nye County in the U.S. state of Nevada. U.S. Route 95 runs through the town, which lies between Tonopah, about to the north and Las Vegas, about to the southeast. State Route 374 connects Beatty to Death Valley National Park, about to the west. Before the arrival of non-indigenous people in the 19th century, the region was home to groups of Western Shoshone. Established in 1905, the community was named after Montillus (Montillion) Murray "Old Man" Beatty, who settled on a ranch in the Oasis Valley in 1896 and became Beatty's first postmaster. With the arrival of the Las Vegas and Tonopah Railroad in 1905, the town became a railway center for the Bullfrog Mining District, including mining towns such as nearby Rhyolite.McCracken, ''History'', pp. 56–59 Starting in the 1940s, Nellis Air Force Base and other federal installations contributed to the town's economy as did tourism related to Death Valley Nationa ...

Pahute Mesa
Pahute Mesa or Paiute Mesa is one of four major nuclear test regions within the Nevada National Security Site (NNSS). It occupies in the northwest corner of the NNSS in Nevada. The eastern section is known as Area 19 and the western section as Area 20. History The Partial Test Ban Treaty of 1963 banned atmospheric nuclear testing. This led to a requirement for an underground test area that could accommodate higher yield tests than Yucca Flat. Pahute Mesa was seen as ideal due to its geology and distance of over from Las Vegas. Holes can be drilled to a depth of more than . This allows tests in the megaton range to be fully contained with minimal ground motion being felt in Las Vegas. Pahute Mesa was thus incorporated into the boundary of the NNSS in late 1963 under an agreement between the United States Atomic Energy Commission and the U.S. Air Force. Geology and climate Pahute Mesa is part of the Tonopah Basin and includes the Silent Canyon caldera complex of the Southwes ...

Amargosa River
The Amargosa River is an intermittent waterway, 185 miles (298 km) long, in southern Nevada and eastern California in the United States. It drains a high desert region, the Amargosa Valley in the Amargosa Desert northwest of Las Vegas, into the Mojave Desert, and finally into Death Valley where it disappears into the ground aquifer. Except for a small portion of its route in the Amargosa Canyon in California and a small portion at Beatty, Nevada, the river flows above ground only after a rare rainstorm washes the region. A 26-mile (42 km) stretch of the river between Shoshone and Dumont Dunes is protected as a National Wild and Scenic River. At the south end of Tecopa Valley the Amargosa River Natural Area protects the habitat. Course Except during flash floods that occur after cloudbursts, most of the course of the Amargosa River is dry on the surface. The flow is generally underground except for stretches near Beatty and near Tecopa, California, in the Amargosa Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amargosa Toad
The Amargosa toad (''Anaxyrus nelsoni'') is a species of toad in the family Bufonidae. It was at one time considered to be a subspecies of the western toad. It is threatened by habitat loss and is classified by the IUCN as being "Critically endangered". Etymology The specific name ''nelsoni'' honors Edward William Nelson, an American naturalist and ethnologist. Distribution and habitat The Amargosa toad is endemic to the Oasis Valley in the Amargosa Desert in Nye County, Nevada, United States. Its natural habitat is along a 10-mile (16 kilometre) stretch of the Amargosa River in the Oasis Valley between Springdale and Beatty, in tributary springs and in nearby isolated springs. The riverside growth consists of cottonwoods, sedges and cattails and breeding takes place in the springs where there is often little aquatic vegetation. Status The International Union for Conservation of Nature has assessed the status of the Amargosa toad as being "critically endangered". Factors ...
