Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."
Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale.
Today, geography is an extremely broad discipline with multiple approaches and modalities. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

Boise National Forest is a National Forest covering 2,203,703 acres (8,918.07 km) of the U.S. state of Idaho. Created on July 1, 1908, from part of Sawtooth National Forest, it is managed by the U.S. Forest Service as five units: the Cascade, Emmett, Idaho City, Lowman, and Mountain Home ranger districts.
The Idaho Batholith underlies most of Boise National Forest, forming the forest's Boise, Salmon River, and West mountain ranges; the forest reaches a maximum elevation of 9,730 feet (2,970 m) on Steel Mountain. Common land cover includes sagebrush steppe and spruce-fir forests; there are 9,600 miles (15,400 km) of streams and rivers and 15,400 acres (62 km) of lakes and reservoirs. Boise National Forest contains 75 percent of the known populations of Sacajawea's bitterroot, a flowering plant endemic to Idaho. (Full article...)
The Doom Bar (previously known as Dunbar sands, Dune-bar, and similar names) is a sandbar at the mouth of the estuary of the River Camel, where it meets the Atlantic Ocean on the north coast of Cornwall, England. Like two other permanent sandbanks further up the estuary, the Doom Bar is composed mainly of marine sand that is continually being carried up from the seabed. More than 60 percent of the sand is derived from marine shells, making it an important source of agricultural lime, which has been collected for hundreds of years; an estimated 10 million tons of sand or more has been removed from the estuary since the early nineteenth century, mainly by dredging.
The estuary mouth, exposed to the Atlantic Ocean, is a highly dynamic environment, and the sands have been prone to dramatic shifts during storms. According to tradition, the Doom Bar formed in the reign of Henry VIII, damaging the prosperity of the port of Padstow a mile up the estuary. (Full article...)
The Mount Cayley volcanic field (MCVF) is a remote volcanic zone on the South Coast of British Columbia, Canada, stretching 31 km (19 mi) from the Pemberton Icefield to the Squamish River. It forms a segment of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc, which extends from Northern California to southwestern British Columbia. Most of the MCVF volcanoes were formed during periods of volcanism under sheets of glacial ice throughout the last glacial period. These subglacial eruptions formed steep, flat-topped volcanoes and subglacial lava domes, most of which have been entirely exposed by deglaciation. However, at least two volcanoes predate the last glacial period and both are highly eroded. The field gets its name from Mount Cayley, a volcanic peak located at the southern end of the Powder Mountain Icefield. This icefield covers much of the central portion of the volcanic field and is one of the several glacial fields in the Pacific Ranges of the Coast Mountains.
Eruptions along the length of the MCVF began between 1.6 and 5.3 million years ago. At least 23 eruptions have occurred throughout its eruptive history. This volcanic activity ranged from effusive to explosive, with magma compositions ranging from basaltic to rhyolitic. Because the MCVF has a high elevation and consists of a cluster of mostly high altitude, non-overlapping volcanoes, subglacial activity is likely to have occurred under less than 800 m (2,600 ft) of glacial ice. The style of this glaciation promoted meltwater escape during eruptions. The steep profile of the volcanic field and its subglacial landforms support this hypothesis. As a result, volcanic features in the MCVF that interacted with glacial ice lack rocks that display evidence of abundant water during eruption, such as hyaloclastite and pillow lava.

Hebron Church (also historically known as Great Capon Church, Hebron Lutheran Church, and Hebron Evangelical Lutheran Church) is a mid-19th-century Lutheran church in Intermont, Hampshire County, in the U.S. state of West Virginia. Hebron Church was founded in 1786 by German settlers in the Cacapon River Valley, making it the first Lutheran church west of the Shenandoah Valley. The congregation worshiped in a log church, which initially served both Lutheran and Reformed denominations. Its congregation was originally German-speaking; the church's documents and religious services were in German until 1821, when records and sermons transitioned to English.
The church's congregation built the present Greek Revival-style 1+1⁄2-story church building in 1849, when it was renamed Hebron on the Cacapon. The original log church was moved across the road and subsequently used as a sexton's house, Sunday school classroom, and public schoolhouse (attended by future West Virginia governor Herman G. Kump). (Full article...)
Banff National Park is Canada's oldest national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley.
The Canadian Pacific Railway was instrumental in Banff's early years, building the Banff Springs Hotel and Chateau Lake Louise, and attracting tourists through extensive advertising. In the early 20th century, roads were built in Banff, at times by war internees from World War I, and through Great Depression-era public works projects. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. (Full article...)
A Halkett boat is a type of lightweight inflatable boat designed by Lt Peter Halkett (1820–1885) during the 1840s. Halkett had long been interested in the difficulties of travelling in the Canadian Arctic, and the problems involved in designing boats light enough to be carried over arduous terrain, but robust enough to be used in extreme weather conditions.
Halkett's first design was a collapsible and inflatable boat made of rubber-impregnated cloth. When deflated, the hull of the boat could be worn as a cloak, the oar used as a walking stick, and the sail as an umbrella. This was followed by a two-man craft that was small enough to fit into a knapsack, and when deflated served as a waterproof blanket. (Full article...)
Black Moshannon State Park is a 3,480-acre (1,410 ha) Pennsylvania state park in Rush Township, Centre County, Pennsylvania, United States. It surrounds Black Moshannon Lake, formed by a dam on Black Moshannon Creek, which has given its name to the lake and park. The park is just west of the Allegheny Front, 9 miles (14 km) east of Philipsburg on Pennsylvania Route 504, and is largely surrounded by Moshannon State Forest. A bog in the park provides a habitat for diverse wildlife not common in other areas of the state, such as carnivorous plants, orchids, and species normally found farther north. As home to the "largest reconstituted bog in Pennsylvania", it was chosen by the Pennsylvania Department of Conservation and Natural Resources for its "25 Must-see Pennsylvania State Parks" list.
Humans have long used the Black Moshannon area for recreational, industrial, and subsistence purposes. The Seneca tribe used it as hunting and fishing grounds. European settlers cleared some land for farming, then clear-cut the vast stands of old-growth white pine and eastern hemlock. Black Moshannon State Park rose from the ashes of a depleted forest which had been largely destroyed by wildfire in the years following the lumber era. The forests were rehabilitated by the Civilian Conservation Corps during the Great Depression in the 1930s. Many of the buildings built by the Civilian Conservation Corps stand in the park today and are protected on the list of National Register of Historic Places in three historic districts.

Elcor is a ghost town, or more properly, an extinct town, in the U.S. state of Minnesota that was inhabited between 1897 and 1956. It was built on the Mesabi Iron Range near the city of Gilbert in St. Louis County. Elcor was its own unincorporated community before it was abandoned and was never a neighborhood proper of the city of Gilbert. Not rating a figure in the national census, the people of Elcor were only generally considered to be citizens of Gilbert. The area where Elcor was located was annexed by Gilbert when its existing city boundaries were expanded after 1969.
In November 1890, the seven Merritt brothers discovered ore near Mountain Iron, triggering an unparalleled iron rush to the Mesabi Range. The Elba mine was opened in 1897, and the town was platted under the direction of Don H. Bacon, president of the Minnesota Iron Company. A second nearby mine, the Corsica, was opened in 1901. The community was first called "Elba" after the name of the first underground mine (the name "Elcor" was formed later by combining the first syllables of each mine's name). The Elba and Corsica mines were both leased by Pickands Mather and Company after the formation of the United States Steel Corporation. An influx of people of many ethnicities and many nations followed, and Elcor became a microcosm of U.S. immigration, mirroring the cultural assimilation of the time. At its peak around 1920, Elcor had two churches, a post office, a general store, a primary school, a railroad station, and its own law enforcement, and housed a population of nearly 1,000.
