Granite
Granite ( ) is a coarse-grained (phanerite, phaneritic) intrusive rock, 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 dike (geology), 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 diagram, 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) conta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Americans Of The United States
Native Americans (also called American Indians, First Americans, or Indigenous Americans) are the Indigenous peoples of the United States, particularly of the lower 48 states and Alaska. They may also include any Americans whose origins lie in any of the indigenous peoples of North or South America. The United States Census Bureau publishes data about "American Indians and Alaska Natives", whom it defines as anyone "having origins in any of the original peoples of North and South America ... and who maintains tribal affiliation or community attachment". The census does not, however, enumerate "Native Americans" as such, noting that the latter term can encompass a broader set of groups, e.g. Native Hawaiians, which it tabulates separately. The European colonization of the Americas from 1492 resulted in a precipitous decline in the size of the Native American population because of newly introduced diseases, including weaponized diseases and biological warfare by colonizers, ...

The Marshall Fire was a destructive wildfire and urban conflagration that started on December 30, 2021, shortly after 11:00 a.m. MST, as a grass fire in Boulder County, Colorado. The fire caused the evacuation of 37,500 people, killed two people, and destroyed more than 991 structures to become the most destructive fire in Colorado history.

This, combined with the lack of snow so far that winter, created ideal weather conditions for wildfires. Additionally, high winds were recorded in the area, with gusts of up to . The winds were driven by the mountain wave effect, and allowed for rapid spread of the fire. Effects of the high winds were also observed on the University of Colorado Boulde ...
