Evidence: 100 • authority: 72

Mount Adams is a stratovolcano located in the Cascade Range of Washington, United States. Standing at 12,276 ft (3,742 m) feet, it is the second-highest mountain in Washington and a prominent feature within the Cascade Volcanic Arc, which formed as a result of the subduction of the Juan de Fuca Plate beneath the North American Plate. Adams is near two more-frequently erupting neighbors, Mount St Helens and Mount Rainier. It has twelve named glaciers descending its slopes. Geologically, Mount Adams first formed in the Pleistocene. Its construction involved multiple eruptive phases, the first around 500,000 years ago, followed by the development of the modern cone around 10,000 years ago. The…

The history of the Philippines dates from the earliest hominin activity in the archipelago at least by 709,000 years ago. Homo luzonensis, a species of archaic humans, was present on the island of Luzon at least by 134,000 years ago. The earliest known anatomically modern human was from Tabon Caves in Palawan dating about 47,000 years. Negrito groups were the first inhabitants to settle in the prehistoric Philippines. These were followed by Austroasiatics, Papuans, and Austronesians. By around 3000 BCE, seafaring Austronesians, who form the majority of the current population, migrated southward from Taiwan. Scholars generally believe that these ethnic and social groups eventually developed…

Mount McLoughlin is a 9,493 ft (2,893 m) dormant steep-sided stratovolcano, or composite volcano, in the Cascade Range of southern Oregon, United States. Located in the Sky Lakes Wilderness, it is one of the volcanic peaks in the Cascade Volcanic Arc, within the High Cascades sector. A prominent landmark for the Rogue River Valley, the mountain is north of Mount Shasta, and south-southwest of Crater Lake. It was named around 1838 after John McLoughlin, a Chief Factor for the Hudson's Bay Company. Mount McLouglin's prominence has made it a landmark to Native Americans and others for thousands of years. McLoughlin consists largely of basaltic andesite. It underwent three major eruptive period…

Mount Kilimanjaro () is a large dormant stratovolcano in Tanzania. It is the highest mountain in Africa and the highest free-standing mountain above sea level in the world, at 5,895 m (19,341 ft) above sea level and 4,900 m (16,100 ft) above its plateau base. It is also the highest volcano in the Eastern Hemisphere and the fourth most prominent peak on Earth. Kilimanjaro's southern and eastern slopes served as the home of the Chagga Kingdoms until their abolition in 1963 by Julius Nyerere. The origin and meaning of the name Kilimanjaro is unknown, but may mean "mountain of greatness" or "unclimbable". Although it is described in classical sources, German missionary Johannes Rebmann is credi…

Repeating Earthquakes During Multiple Phases of Unrest and Eruption at Mount Agung, Bali, Indonesia, 2017. In 2017, Mount Agung produced a small (VEI 2) eruption that was preceded by an energetic volcano-tectonic (VT) swarm (>800 earthquakes per day up to M4.9) and two months of declining activity. The period of decreased seismic activity complicated forecasting efforts for scientists monitoring the volcano. We examine the time history of earthquake families at Mount Agung in search of additional insight into the temporal changes in the shallow crust prior to eruption. Specifically, we analyze the period of declining seismic activity about five weeks prior to the eruption when forecasting u…

Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed a system of image-making called the Zone System, a method of achieving a desired final print through a technical understanding of how the tonal range of an image is the result of choices made in exposure, negative development, and printing. Adams was a life-long advocate for environmental conservation, and his photographic p…

Impact of intermittent lead exposure on hominid brain evolution.. Gene-environmental interactions shape the evolution of brain architecture and function. Neuro-oncological ventral antigen 1 ( NOVA1 ) is one gene that distinguishes modern humans from extinct hominids. However, the evolutionary pressures that selected the modern NOVA1 allele remain elusive. Here, we show using fossil teeth that several hominids ( Australopithecus africanus , Paranthropus robustus , early Homo sp., Gigantopithecus blacki , Pongo sp., Homo neanderthalensis , and Homo sapiens ) were consistently exposed to lead over 2 million years, contradicting the idea that lead exposure is solely a modern phenomenon.
