Alsek River
The Alsek River (; Tlingit ''Aalseix̱' '') is a wilderness river flowing from Yukon into Northern British Columbia and into Alaska. It enters the Gulf of Alaska at Dry Bay. Most of the Alsek River's basin is within protected wilderness areas and National Parks. The Alsek and its main tributary, the Tatshenshini River, are part of the Canadian Heritage Rivers System and a UNESCO World Heritage Site. In the year 2016, the Alsek River captured the flow of the Slims River due to the retreat of Kaskawulsh Glacier. Researchers attributed the change in flow to human-caused climate change; this was the first time human-caused climate change was implicated in the reorganization of a river. Research indicates that in a few decades, Alsek River may further change its final course. The rapidly retreating Grand Plateau Glacier separates Alsek River and lake from nearby Grand Plateau Lake. Geologists predict that when the two lakes merge, Alsek River will abandon its current outlet in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Kaskawulsh Glacier
The Kaskawulsh Glacier is a vast, temperate valley glacier nestled in the St. Elias Mountains, within Kluane National Park in the Canadian territory of Yukon. Geography Located approximately above sea level, the glacier covers more than of the surrounding landscape. It terminates at the head of two river valleys, the Slims and the Kaskawulsh River, which feed the Yukon River (via Kluane Lake) and Alsek River systems respectively. The Kaskawulsh is the result of two converging outlet glaciers, the Central and North Arms, and is an impressive wide at its broadest point. Waterflow Until 2016, abundant melt water from the Kaskawulsh was channeled by ice dam to drain through the Slims River, north to Kluane Lake, and ultimately to the Bering Sea. In 2016, as the glacier receded, the predominant flow abruptly switched to the Kaskawulsh River, flowing east and then south to Alsek River and to the Gulf of Alaska. As the water level at Kluane Lake continues to drop, researchers expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

First Nations In Canada
First Nations (french: Premières Nations) is a term used to identify those Indigenous Canadian peoples who are neither Inuit nor Métis. Traditionally, First Nations in Canada were peoples who lived south of the tree line, and mainly south of the Arctic Circle. There are 634 recognized First Nations governments or bands across Canada. Roughly half are located in the provinces of Ontario and British Columbia. Under Charter jurisprudence, First Nations are a "designated group," along with women, visible minorities, and people with physical or mental disabilities. First Nations are not defined as a visible minority by the criteria of Statistics Canada. North American indigenous peoples have cultures spanning thousands of years. Some of their oral traditions accurately describe historical events, such as the Cascadia earthquake of 1700 and the 18th-century Tseax Cone eruption. Written records began with the arrival of European explorers and colonists during the Age of Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raft
A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrels, or inflated air chambers (such as pontoons), and are typically not propelled by an engine. Rafts are an ancient mode of transport; naturally-occurring rafts such as entwined vegetation and pieces of wood have been used to traverse water since the dawn of humanity. Human-made rafts Traditional or primitive rafts were constructed of wood or reeds. Modern rafts may also use pontoons, drums, or extruded polystyrene Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a ... blocks. Inflatable rafts up to the 20th century used flotation chambers ...

Kayak
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word ''qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and "fli ...

Alaska Panhandle
Southeast Alaska, colloquially referred to as the Alaska(n) Panhandle, is the southeastern portion of the U.S. state of Alaska, bordered to the east and north by the northern half of the Canadian province of British Columbia (and a small part the Yukon Territories). The majority of Southeast Alaska's area is part of the Tongass National Forest, the United States' largest national forest. In many places, the international border runs along the crest of the Boundary Ranges of the Coast Mountains (see Alaska boundary dispute). The region is noted for its scenery and mild, rainy climate. The largest cities in the region are Juneau, Sitka, and Ketchikan. This region is also home to Hyder, the easternmost town in Alaska. Geography Southeast Alaska has a land area of , comprising much of the Alexander Archipelago. The largest islands are, from North to South, Chichagof Island, Admiralty Island, Baranof Island, Kupreanof Island, Revillagigedo Island and Prince of Wales Island. Maj ...
