The upper part of the Crooked River Gorge, which are also popular among climbers, are made of columnar basalt cliffs eroded by the Crooked River since the Newberry volcanic eruption 1.2 million years ago.Dunegan, Lizann (2009).''Best Easy Day Hikes Bend and Central Oregon'' Falcon, 2nd ed. p. 25, References External links Oregon Field Guide: ''Crooked River Gorge Cleanup'', 1993 Landforms of Jefferson County, Oregon Canyons and gorges of Oregon {{JeffersonCountyOR-geo-stub ...

Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Smith Rock State Park
Smith Rock State Park is a state park located in central Oregon's High Desert near the communities of Redmond and Terrebonne. The day-use area of the park is open daily from dawn to dusk. The park also has a camping area as well that accommodates tent camping only. Its sheer cliffs of tuff and basalt are ideal for rock climbing of all difficulty levels. Smith Rock is generally considered the birthplace of modern American sport climbing, and is host to cutting-edge climbing routes. It is popular for sport climbing, traditional climbing, multi-pitch climbing, and bouldering. History The origin of the Smith Rock name is uncertain. One story, published the Albany ''States Rights Democrat'' in 1867, states that Smith Rock was named after John Smith, who was Linn County Sheriff and an Oregon state legislator in the 1850s and 1860s. The newspaper article credits Smith with "discovering" the rock. Another story claims the rock was named after a soldier named Smith who fell to hi ...

Central Oregon
Central Oregon is a geographic region in the U.S. state of Oregon and is traditionally considered to be made up of Deschutes, Jefferson, and Crook counties. Other definitions include larger areas, often encompassing areas to the north towards the Columbia River, eastward towards Burns, or south towards Klamath Falls. These three counties have a combined population of 200,431 as of the 2010 census, with Deschutes the largest of the three counties, having approximately four times the population of the other two counties combined. As of 2015, the most populous city in the region is Bend, with an estimated 87,014 residents. As defined by the three county definition, Central Oregon covers of land. Central Oregon has had 3 record tourism years beginning in 2012. Over 2.2 million people visited Central Oregon in 2012 and again in 2013. The region is located in the middle of the state with the Cascades to the west dividing the state from north to south, and the smaller Ochoco Mountai ...

Columnar Basalt
Basalt (; ) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of Venus, which cover ~80% of the surface, are basaltic; the lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flows that can spread over great areas before cooling and solidifying. Flood basalts are thick sequence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crooked River (Oregon)
The Crooked River is a tributary, long, of the Deschutes River in the U.S. state of Oregon. The river begins at the confluence of the South Fork Crooked River and Beaver Creek. Of the two tributaries, the South Fork Crooked River is the larger and is sometimes considered part of the Crooked River proper. A variant name of the South Fork Crooked River is simply "Crooked River". The Deschutes River flows north into the Columbia River. Course The South Fork Crooked River originates in an area called Misery Flat, along the Deschutes County, Lake County and Harney County boundaries, north of Glass Buttes. The South Fork's tributaries drain Hampton Buttes to the west and Mackey Butte to the east. The South Fork Crooked River flows north for , collecting tributaries including Buck Creek and Twelvemile Creek before joining Beaver Creek to form the Crooked River proper near Paulina in Crook County. Beaver Creek arises in two forks, North Fork and South Fork Beaver Creek, in Grant Coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newberry Volcano
Newberry Volcano is a large active shield-shaped stratovolcano located about south of Bend, Oregon, United States, east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. The largest volcano in the Cascade Volcanic Arc, Newberry has an area of when its lava flows are taken into account. From north to south, the volcano has a length of , with a width of and a total volume of approximately . It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855. The surrounding area has been inhabited by Native American populations for more than 10,000 years. The volcano contains a large caldera, in diameter, known as the Newberry Caldera. Within the caldera are two lakes: Paulina Lake and East Lake. The volcano and its vicinity include many pyroclastic cones, lava flows and lava domes; Newberry has more than 400 vents, the most of a ...

Landforms Of Jefferson County, Oregon
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
