Seward Mountains (Alaska)
The Seward Mountains is a small mountain range in southeastern Alaska, United States, located on the upper Portland Canal. It has an area of 107 km2 and is a subrange of the Boundary Ranges which in turn form part of the Coast Mountains. Part of the eastern border of Misty Fjords National Monument transects the range. Despite its name, the Seward Mountains are located nowhere near Seward, Alaska or the Seward Peninsula, though the Seward Peninsula has its own set of four maintain ranges: the Kigluaik Mountains, Bendeleben Mountains, Darby Mountains, and York Mountains.

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii.

Portland Canal
Portland Canal is an arm of Portland Inlet, one of the principal inlets of the British Columbia Coast. It is approximately long. The Portland Canal forms part of the border between southeastern Alaska and British Columbia. The name of the entire inlet in the Nisga'a language is ', with meaning "at the back of (someplace)". The upper end of the inlet was home to the Tsetsaut ( in Nisgaʼa), who after being decimated by war and disease were taken under the protection of the Laxsgiik (Eagle) chief of the Nisgaʼa, who holds the inlet's title in native law. Despite its naming as a canal, the inlet is a fjord, a completely natural and not man-made geographic feature, and extends northward from the Portland Inlet at Pearse Island, British Columbia, to Stewart, British Columbia, and Hyder, Alaska. Observatory Inlet joins the Portland Canal at Ramsden Point, where both merge with Portland Inlet. Pearse Canal joins Portland Canal at the north end of Pearse Island. Portland C ...

Seward Peninsula
The Seward Peninsula is a large peninsula on the western coast of the U.S. state of Alaska whose westernmost point is Cape Prince of Wales. The peninsula projects about into the Bering Sea between Norton Sound, the Bering Strait, the Chukchi Sea, and Kotzebue Sound, just below the Arctic Circle. The entire peninsula is about long and wide. Like Seward, Alaska, it was named after William H. Seward, the United States Secretary of State who fought for the U.S. purchase of Alaska. The Seward Peninsula is a remnant of the Bering land bridge, a roughly thousand-mile-wide swath of land connecting Siberia with mainland Alaska during the Pleistocene Ice Age. This land bridge aided in the migration of humans, as well as plant and animal species, from Asia to North America. Excavations at sites such as the Trail Creek Caves and Cape Espenberg in the Bering Land Bridge National Preserve as well as Cape Denbigh to the south have provided insight into the timeline of prehistorical ...
