Larch Mountain (Clark County, Washington)
Larch Mountain, elevation , is the highest free-standing peak in Clark County, Washington. (The andesite plugs Pyramid Rock and Sturgeon Rock are higher but are outcroppings on ridges of Silver Star Mountain.) It is laced by a network of gravel roads as part of the Yacolt Burn State Forest. The eastern flank of the mountain was scorched by a gigantic forest fire in September 1902 and subsequently experienced a massive rockslide that rendered that side mostly unvegetated. The southern section of the mountain is part of the Jones Creek Off-Road Vehicle recreation area. From the picnic area at the top, the view is west toward the Vancouver, Washington area and east to Silver Star. A minimum security prison/work camp is situated nearby, whose inmates construct fire roads, fire trails, maintain campgrounds and help fight fires in the area.

Cascade Range
The Cascade Range or Cascades is a major mountain range of western North America, extending from southern British Columbia through Washington and Oregon to Northern California. It includes both non-volcanic mountains, such as the North Cascades, and the notable volcanoes known as the High Cascades. The small part of the range in British Columbia is referred to as the Canadian Cascades or, locally, as the Cascade Mountains. The latter term is also sometimes used by Washington residents to refer to the Washington section of the Cascades in addition to North Cascades, the more usual U.S. term, as in North Cascades National Park. The highest peak in the range is Mount Rainier in Washington at . part of the Pacific Ocean's Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the eruptions in the contiguous United States over the last 200 years have been from Cascade volcanoes. The two most recent were Lassen Peak from 1914 to 1921 and ...

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Geology of Mars, Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silver Star Mountain (Skamania County, Washington)
Silver Star Mountain is a recently uplifted ridge of older Western Cascades volcanic rock, underlain by a granitic pluton of similar Western Cascades age, located in the Cascade Range in the U.S. state of Washington. Consisting of late Eocene to Oligocene epoch rock, it lies within the Gifford Pinchot National Forest. Silver Star is composed of three lithologic units (distinct units of rock, each with different physical characteristics), including the large Silver Star Granodiorite unit. Silver Star Mountain and the surrounding area, in contrast to the rest of the local backcountry, has a ridge-like appearance, creating a striking skyline similar to mountains further north in the Cascade Range. The area lacks trees, and comprises steep cliffs, talus slopes, and meadows filled with wildflowers. The mountain can be hiked and has been noted for its trails by local mountaineers.

Mountains Of Washington (state)
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 ...
