Grizzly Peak (Sawatch Range)
Grizzly Peak is a high and prominent mountain summit of the Collegiate Peaks in the Sawatch Range of the Rocky Mountains of North America. The thirteener is located south-southwest ( bearing 202°) of Independence Pass, Colorado, United States, on the Continental Divide separating San Isabel National Forest and Chaffee County from White River National Forest and Pitkin County. Elevation Grizzly Peak is the highest summit in the United States less than , making it the highest thirteener in the country. At one time, the peak's elevation was measured to be over 14,000 feet and was believed to be a fourteener, but more recent and accurate surveys have dropped it below that threshold. Geology The mountain is composed of andesite lava flows and breccias of Oligocene age.

Rocky Mountains
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in great-circle distance, straight-line distance from the northernmost part of Western Canada, to New Mexico in the Southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of Rocky Mountain Trench, the Trench, or in the northeastern foothills of the Brooks Range/British Mountains that face the Beaufort Sea coasts between the Canning River (Alaska), Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque metropolitan area, Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountains, Sandia–Manzano Mountain Range.

San Juan Mountains
The San Juan Mountains is a high and rugged mountain range in the Rocky Mountains in southwestern Colorado and northwestern New Mexico. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range. The last large-scale mines were the Sunnyside Mine near Silverton, which operated until late in the 20th century, and the Idarado Mine on Red Mountain Pass, which closed in the 1970s. Famous old San Juan mines include the Camp Bird and Smuggler Union mines, both located between Telluride and Ouray. The Summitville mine was the scene of a major environmental disaster in the 1990s when the liner of a cyanide-laced tailing pond began leaking heavily. Summitville is in the Summitville caldera, one ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grizzly Peak (Dolores/San Juan Counties, Colorado)
Grizzly Peak is a mountain summit on the boundary shared by Dolores County and San Juan County, in Colorado, United States. Description Grizzly Peak is set west of the Continental Divide in the San Juan Mountains which are a subrange of the Rocky Mountains. The peak is located north of Durango and northwest of Engineer Mountain, on land managed by San Juan National Forest. Grizzly ranks as the fourth-highest peak in Dolores County and 126th-highest in Colorado. Precipitation runoff from the mountain's west slope drains to the Dolores River via Twin Creek, and the east slope drains into Cascade Creek which is a tributary of the Animas River. Topographic relief is significant as the summit rises nearly above Cascade Creek in 0.65 mile (1.05 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names, and has been printed in publications since 1899.Henry Gannett, United States Geological Survey (1899), ''A Dictionary of Alt ...

Breccia
Breccia ( , ; ) is a rock composed of large angular broken fragments of minerals or Rock (geology), rocks cementation (geology), cemented together by a fine-grained matrix (geology), matrix. The word has its origins in the Italian language, in which it means "rubble". A breccia may have a variety of different origins, as indicated by the named types including sedimentary breccia, fault (geology), fault or tectonics, tectonic breccia, igneous breccia, Impact event, impact breccia, and Hydrothermal circulation, hydrothermal breccia. A megabreccia is a breccia composed of very large rock fragments, sometimes kilometers across, which can be formed by landslides, impact events, or caldera collapse. Types Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like Conglomerate (geology), conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from Conglomerate (geol ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) to porphyritic (coarse-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
