Falls Creek (California)
Falls Creek, also known as the Falls River, is a tributary of the Tuolumne River in Yosemite National Park, California, United States. The creek begins at the northern boundary of the national park and flows U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 11, 2011 to empty into the Tuolumne at Hetch Hetchy Reservoir, dropping over two well-known waterfalls. The Pacific Crest Trail and other national park trails follow the creek for much of its course. Course Falls Creek begins at Dorothy Lake, which is located at one of the northernmost points in the national park. The headwaters, at nearly in elevation, lie between Forsyth Peak, Dorothy Lake Pass, Bond Pass and Bigelow Peak. It plunges into Jack Main Canyon, paralleling the Pacific Crest Trail, which carries it south to round Chittenden Peak, where Tilden Creek enters from the left. From there the creek passes Branigan Lake, then cascades down into the basi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuolumne River
The Tuolumne River ( Yokutsan: ''Tawalimnu'') flows for through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of , carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity. Humans have inhabited the Tuolumne River area for up to 10,000 years. Prior to the arrival of Europeans, the river canyon provided an important summer hunting ground and a trade route between Native Americans in the Central Valley to the west and the Great Basin to the east. First named in 1806 by a Spanish explorer after a nearby indigenous village, the Tuolumne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rancheria Creek (Tuolumne County, California)
Rancheria Creek is a long stream in northern Yosemite National Park mostly in Tuolumne County, California and is a tributary of the Tuolumne River. Draining a large area of the Sierra Nevada, it is the largest tributary of the Tuolumne within Yosemite National Park. The stream is labeled as Kerrick Creek on some early maps. The creek begins at Peeler Lake at the Sierra Crest, in Mono County, and immediately crosses westward into Tuolumne County. It flows in a southerly direction through Kerrick Meadow and a series of high mountain valleys until reaching Kerrick Canyon, where it turns abruptly west. The Pacific Crest Trail parallels the creek through Kerrick Canyon. At the end of the canyon it receives a major tributary from Stubblefield Canyon and turns southwest, receiving Tilden Creek. Continuing southwest, it flows through rugged and complex granite formations, receives Breeze Creek, then turns west once more for its last few miles. It drops over Rancheria Falls before empty ...

Ranger Station
A ranger station is a building complex typically including a dwelling and outbuildings which support a ranger or other guardian of a wilderness or national forest area. For example, the Cold Meadows Guard Station in Idaho County, Idaho, United States, is a complex of six buildings and structures in the Payette National Forest The Payette National Forest is a U.S. National Forest located in central western Idaho, in parts of Valley, Idaho, Adams, and Washington counties. The land area consists of approximately 2.3 million acres (9,300 km2) of federally managed .... With . References Ranger stations {{Architecture-stub ...

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Glaciation
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state. Quaternary Period Within the Quaternary, which started about 2.6 million years before present, there have been a number of glacials and interglacials. At least eight glacial cycles have occurred in the last 740,000 years alone. Penultimate Glacial Period The Penultimate Glacial Period (PGP) is the glacial period that occurred before the Last Glacial Period. It began about 194,000 years ago and ended 135,000 years ago, with the beginning of the Eemian interglacial. Last Glacial Period The last glacial period was the most recent glacial period ...

San Joaquin River
The San Joaquin River (; es, RÃo San JoaquÃn) is the longest river of Central California. The long river starts in the high Sierra Nevada, and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean. An important source of irrigation water as well as a wildlife corridor, the San Joaquin is among the most heavily dammed and diverted of California's rivers. People have inhabited the San Joaquin Valley for more than 8,000 years, and it was long one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin. When Spain colonized the area, they sent soldiers from Mexico, who were usually of mixed native Mexican and Spanish birth, led by Spanish officers. Franciscan missionaries from Spain came with the expeditions to evangelize the natives by teac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
