Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The density of jasper is typically 2.5 to 2.9 g/cm3. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper.
The Black Rock Desert is a semi-arid region of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa 100 miles (160 km) north of Reno, Nevada, that encompasses more than 300,000 acres (120,000 ha) of land and contains more than 120 miles (200 km) of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan.
The Salmon River, also known as the "River of No Return", is a river located in the U.S. state of Idaho in the western United States. It flows for 425 miles (685 km) through central Idaho, draining a rugged, thinly populated watershed of 14,000 square miles (36,000 km2). The river drops more than 7,000 feet (2,100 m) from its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, to its confluence with the Snake River. Measured at White Bird, its average discharge is 11,060 cubic feet per second. The Salmon River is the longest undammed river in the contiguous United States.
The Owyhee River is a tributary of the Snake River located in northern Nevada, southwestern Idaho and southeastern Oregon in the Western United States and its Pacific Northwest region. It is 280 miles (450 km) long. The river's drainage basin is 11,049 square miles (28,620 km2) in area, one of the largest subbasins of the Columbia River Basin with its major waterways of the Columbia River and Snake River. The mean annual discharge is 995 cubic feet per second (28.2 m3/s), with a maximum of 50,000 cu ft/s (1,400 m3/s) recorded in 1993 and a minimum of 42 cu ft/s (1.2 m3/s) in 1954.
Goose Creek may refer to the following places:
The Palouse River is a tributary of the Snake River in Washington and Idaho, in the northwest United States. It flows for 167 miles (269 km) southwestwards, primarily through the Palouse region of southeastern Washington. It is part of the Columbia River Basin, as the Snake River is a tributary of the Columbia River.
Goose Hollow is a neighborhood in southwest Portland, Oregon. It acquired its distinctive name through early residents' practice of letting their geese run free in Tanner Creek Gulch and near the wooded ravine in the Tualatin Mountains known as the Tanner Creek Canyon. Tanner Creek Gulch was a 20-block-long, 50-foot-deep (15 m) gulch that started around SW 17th and Jefferson and carried the waters of Tanner Creek into Couch Lake. Over a century ago, Tanner Creek was buried 50 feet (15 m) underground, and the Tanner Creek Gulch was filled in. The only remaining part of the hollow is the ravine, Tanner Creek Canyon, carved out by Tanner Creek through which The Sunset Highway carrying US-26 passes and which the Vista Bridge spans, also called the Vista Viaduct.
Burke is a ghost town in Shoshone County, Idaho, United States, established in 1887. Once a thriving silver, lead and zinc mining community, the town saw significant decline in the mid-twentieth century after the closure of several mines.
Burke Canyon is the canyon of the Burke-Canyon Creek, which runs through the northernmost part of Shoshone County, Idaho, U.S., within the northeastern Silver Valley. A hotbed for mining in the late-nineteenth and twentieth centuries, Burke Canyon now contains several ghost towns and remnants of former communities along Idaho State Highway 4, which runs northeast through the narrow canyon to the Montana border.
In the United States, gold mining has taken place continually since the discovery of gold at the Reed farm in North Carolina in 1799. The first documented occurrence of gold was in Virginia in 1782. Some minor gold production took place in North Carolina as early as 1793, but created no excitement. The discovery on the Reed farm in 1799 which was identified as gold in 1802 and subsequently mined marked the first commercial production.
The Little Salmon River is a tributary of the Salmon River in Idaho in the western United States. The river is approximately 51 miles (82 km) in length and drains 576 square miles (1,490 km2) of land.
The Bass Formation, also known as the Bass Limestone, is a Mesoproterozoic rock formation that outcrops in the eastern Grand Canyon, Coconino County, Arizona. The Bass Formation erodes as either cliffs or stair-stepped cliffs. In the case of the stair-stepped topography, resistant dolomite layers form risers and argillite layers form steep treads. In general, the Bass Formation in the Grand Canyon region and associated strata of the Unkar Group-rocks dip northeast (10°–30°) toward normal faults that dip 60+° toward the southwest. This can be seen at the Palisades fault in the eastern part of the main Unkar Group outcrop area. In addition, thick, prominent, and dark-colored basaltic sills intrude across the Bass Formation.
St. Peter's Dome is a granite-topped peak on Pikes Peak massif in the Pike National Forest. The peak, at 9,528 feet (2,904 m) in elevation, is located in El Paso County, Colorado, above Colorado Springs. It is located about 8 miles (13 km) from Colorado Springs along Old Stage and Gold Camp Roads. Old Stage Road is picked up behind The Broadmoor and Gold Camp Road winds through Cheyenne Canyon.
The Rock Flat Placer is a small placer deposit in central Idaho which is part of the Meadows Mining District. It is known to produce gold, corundum, garnet, zircon, monazite, chromite, ilmenite, magnetite, platinum, topaz, and spinel. Additionally, it is known to produce the occasional diamond, but the last one found was in the 1920s.
