List Of U.S. National Parks By Elevation
This is a list of United States National Parks by elevation. Most of America's national parks are located in mountainous areas. Even among those located close to the ocean, not all are flat. Those few that are low-lying preserve important natural habitats that could never exist at high altitudes. Several national parks protect deep canyons with great vertical relief. There are also three national parks whose primary features are caves, the depths of which are still being explored. Highest and lowest points in each US National Park ''Criteria:'' Points on this list are the highest and lowest points within each national park and its associated national preserve, if it has one. It does not include adjacent or associated national recreation areas, parkways, memorials, or forests, but does include private property within park boundaries. Footnotes are given to mention other notable high or low points, when appropriate. Selected Profiles The AT thru the Smokeys– The Appalachian ...

Telescope Peak - Death Valley NP California
A telescope is a device used to observe distant objects by their emission, Absorption (electromagnetic radiation), absorption, or Reflection (physics), reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telesc ...
