O'Malley Peak
O'Malley Peak is a mountain summit located in the Chugach Mountains, in Anchorage Municipality in the U.S. state of Alaska. O'Malley Peak is situated in Chugach State Park, southeast of downtown Anchorage, west of Mount Williwaw, and northwest of The Ramp, which is its nearest higher peak. Access is via the Powerline Trail with several scramble routes to the summit. Dr. James O'Malley "Doc" O'Malley moved to Anchorage in 1946 and practiced medicine there until his death in 1974. He was one of the first doctors in town, respected by his peers and beloved by patients. There is also a school and road named after him in Anchorage.Anchorage Daily Times - obituary of Dr. O'Malley - August 12, 1974 Climate Based on the Köppen climate classification, O'Malley Peak is located in a subarctic climate zone with long, cold, snowy winters, and mild summers.

Chugach Mountains
The Chugach Mountains of southern Alaska are the northernmost of the several mountain ranges that make up the Pacific Coast Ranges of the western edge of North America. The range is about long and wide, and extends from the Knik and Turnagain Arms of the Cook Inlet on the west to Bering Glacier, Tana Glacier, and the Tana River on the east. It is bounded on the north by the Matanuska, Copper, and Chitina rivers. The highest point of the Chugach Mountains is Mount Marcus Baker, at , but with an average elevation of , most of its summits are not especially high. Even so, its position along the Gulf of Alaska ensures more snowfall in the Chugach than anywhere else in the world, an annual average of over 1500 cm (800 in).Steep, Freeskiing Documentary, 2007 The mountains are protected in the Chugach State Park and the Chugach National Forest. Near to Anchorage, they are a popular destination for outdoor activities. The Richardson Highway, Seward Highway, Portage G ...

Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Grea ...

Mountains Of Alaska
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

Flattop Mountain (Anchorage, Alaska)
Flattop Mountain is a mountain in the U.S. state of Alaska, located in Chugach State Park just east of urban Anchorage. It is the most climbed mountain in the state. It is usually reached by driving to the Glen Alps trailhead and following a well-maintained 1.5-mile (2.4-km) trail, with an elevation gain of 1280 feet (390 m) from the parking lot to the plateau. Off the plateau loop is a difficult trail to the peak. Since it is the most accessible mountain to Anchorage, Flattop is a very popular location for hiking, climbing, berry picking, paragliding, and backcountry skiing. Campouts are held on the summit at the summer and winter solstices. Flattop is known for its panoramic views of Anchorage and the surrounding area; Denali, Mount Foraker, and Mount Spurr Mount Spurr ( Dena'ina: ''K'idazq'eni'') is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1 ...

Campbell Creek (Alaska)
Campbell Creek ( Dena'ina: ''Qin Cheghitnu'') is one of several streams that flow through the city of Anchorage, Alaska. It runs for from the Chugach Mountains to the Turnagain Arm of Cook Inlet. The main stem of the creek is formed at the junction of the North and South Forks, which flows in a south-westerly direction through Campbell Lake, before reaching the Turnagain Arm. The watershed of the Campbell Creek includes a number of tributaries, including the Little Campbell Creek, the Lower Campbell Creek, and the Middle Fork. The creek connects a number of parks, open spaces and lakes to form a green corridor running from east to west through the city. The paved Campbell Creek trail follows the creek for much of its lower course through the areas from Campbell Park to Campbell Lake, over a distance of seven miles. History Before English-speaking settlers arrived in Anchorage, the Dena'ina inhabited the area. They called the creek Qin Cheghitnu or Crying Ridge Creek. The Cryi ...

Snow Covered Chugach Mountains
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Alaska
Alaska occupies the northwestern portion of the North American continent and is bordered only by Canada on the east. It is one of two U.S. states not bordered by another state; Hawaii is the other. Alaska has more ocean coastline than all of the other U.S. states combined. About of Canadian territory separate Alaska from Washington state. Alaska is thus an exclave of the United States that is part of the continental U.S. and the U.S. West Coast, but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent. The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, Russia ( Chukotka Autonomous Okrug), Bering Sea, the Bering Strait, and Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north. Because it extends into the Eastern Hemisphere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
