In the Nebraska license plate system, Morrill County is represented by the prefix 64 (it had the 64th-largest number of vehicles registered in the state when the license plate system was established in 1922).

Rocky Mountain Rendezvous
The Rocky Mountain Rendezvous was an annual rendezvous, held between 1825 to 1840 at various locations, organized by a fur trading company at which trappers and mountain men sold their furs and hides and replenished their supplies. The fur companies assembled teamster-driven mule trains which carried whiskey and supplies to a pre-announced location each spring-summer and set up a trading fair (the rendezvous). At the end of the rendezvous, the teamsters packed the furs out, either to Fort Vancouver in the Pacific Northwest for the British companies or to one of the northern Missouri River ports such as St. Joseph, Missouri, for American companies. Early explorer and trader Jacques La Ramee organized a group of independent free trappers to the first ever gathering as early as 1815 at the junction of the North Platte and Laramie Rivers after befriending numerous native American tribes. Rendezvous were known to be lively, joyous places, where all were allowed—fur trappers, Indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Independence Rock (Wyoming)
Independence Rock is a large granite rock, approximately high, long, and wide, which is in southwestern Natrona County, Wyoming along Wyoming Highway 220.

National Historic Sites (United States)
National Historic Site (NHS) is a designation for an officially recognized area of national historic significance in the United States. An NHS usually contains a single historical feature directly associated with its subject. The National Historical Park (NHP) is an area that generally extends beyond single properties or buildings, and its resources include a mix of historic and later structures and sometimes significant natural features. As of 2022, there are 62 NHPs and 83 NHSs. Most NHPs and NHSs are managed by the National Park Service (NPS). Some federally designated sites are owned by local authorities or privately owned, but are authorized to request assistance from the NPS as affiliated areas. One property managed by the U.S. Forest Service: Grey Towers National Historic Site. As of October 15, 1966, all historic areas, including NHPs and NHSs, in the NPS are automatically listed on the National Register of Historic Places (NRHP). There are also about 90,000 NRHP sites, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chimney Rock Close-Up
A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator, or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or chimney effect. The space inside a chimney is called the ''flue''. Chimneys are adjacent to large industrial refineries, fossil fuel combustion facilities or part of buildings, steam locomotives and ships. In the United States, the term ''smokestack industry'' refers to the environmental impacts of burning fossil fuels by industrial society, including the electric industry during its earliest history. The term ''smokestack'' (colloquially, ''stack'') is also used when referring to locomotive chimneys or ship chimneys, and the term ''funnel'' can also be used. The height of a chimn ...

Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcano, volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal a ...
