Sierra Madera Crater
Sierra Madera crater is a meteorite crater (astrobleme) in southwestern Pecos County, Texas, United States. The central peak of the rebound structure of the impact crater rises above the surrounding land. The peak is visible from U.S. Highway 385 between Fort Stockton, Texas and Marathon, Texas. The Sierra Madera crater is located on private property on the La Escalera Ranch. It is in diameter and the age is estimated to be less than 100 million years (Cretaceous or younger). Apollo 17's Gene Cernan and Jack Schmitt did some of their geologic training here.

Jack Schmitt
Harrison Hagan Schmitt (born July 3, 1935) is an American geologist, retired NASA astronaut, university professor, former U.S. senator from New Mexico, and the most recent living person—and only person without a background in military aviation—to have walked on the Moon. In December 1972, as one of the crew onboard Apollo 17, Schmitt became the first member of NASA Astronaut Group 4, NASA's first scientist-astronaut group to fly in space. As Apollo 17 was the last of the Apollo program, Apollo missions, he also became the List of Apollo astronauts#People who have walked on the Moon, twelfth and second-youngest person to set foot on the Moon and the second-to-last person to step off of the Moon (he boarded the Apollo Lunar Module, Lunar Module shortly before commander Eugene Cernan). Schmitt also remains the only professional scientist to have flown beyond low Earth orbit and to have visited the Moon. He was influential within the community of geologists supporting the Apollo p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Llano Estacado
The Llano Estacado (), sometimes translated into English as the Staked Plains, is a region in the Southwestern United States that encompasses parts of eastern New Mexico and northwestern Texas. One of the largest mesas or tablelands on the North American continent, the elevation rises from in the southeast to over in the northwest, sloping almost uniformly at about . Naming The Spanish name is often interpreted as meaning "Staked Plains", although "stockaded" or "palisaded plains" have also been proposed, in which case the name would derive from the steep escarpments on the eastern, northern, and western periphery of the plains. Leatherwood writes that Francisco Coronado and other European explorers described the Mescalero Ridge on the western boundary as resembling "palisades, ramparts, or stockades" of a fort, but does not present the original Spanish. In ''Beyond the Mississippi'' (1867), Albert D. Richardson, who traversed the region from east to west in October 1859, wrote ...

Pecos River
The Pecos River ( es, Río Pecos) originates in north-central New Mexico and flows into Texas, emptying into the Rio Grande. Its headwaters are on the eastern slope of the Sangre de Cristo mountain range in Mora County north of Pecos, New Mexico, at an elevation of over 12,000 feet (3,700 m). The river flows for 926 miles (1,490 km) before reaching the Rio Grande near Del Rio. Its drainage basin encompasses about 44,300 square miles (115,000 km2).Largest Rivers of the United States USGS The name "Pecos" derives from the (Native American language) term for the |
Trans-Pecos
The Trans-Pecos, as originally defined in 1887 by the Texas geologist Robert T. Hill, is the portion of Texas that lies west of the Pecos River. The term is considered synonymous with Far West Texas, a subdivision of West Texas. The Trans-Pecos is part of the Chihuahuan Desert, the largest desert in North America. It is the most mountainous and arid portion of the state, and most of its vast area (outside the city of El Paso) is sparsely populated. Among the nine counties in the region are the five largest counties by area in Texas and eight of the eleven largest in the state. The area is known for the natural environment of the Big Bend and the gorge of the Rio Grande, part of which has been designated a National Wild and Scenic Rivers System. With the notable exceptions of Big Bend Ranch State Park, Big Bend National Park and the Guadalupe Mountains National Park, the vast majority of the Trans-Pecos region consists of privately owned ranchland. However, most of the region ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteor Crater
Meteor Crater, or Barringer Crater, is a meteorite impact crater about east of Flagstaff and west of Winslow in the desert of northern Arizona, United States. The site had several earlier names, and fragments of the meteorite are officially called the Canyon Diablo Meteorite, after the adjacent Cañon Diablo. Because the United States Board on Geographic Names recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor. Meteor Crater lies at an elevation of above sea level. It is about in diameter, some deep, and is surrounded by a rim that rises above the surrounding plains. The center of the crater is filled with of rubble lying above crater bedrock. One of the interesting features of the crater is its squared-off outline, believed to be caused by existing regional jointing (cracks) in the strata at the impact site. Despite historic attempts to make the crater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marquez Crater
Marquez crater is a meteorite impact crater, crater located in Leon County, Texas, Leon County, Texas near the small town of Marquez, Texas, Marquez about northeast of Austin, Texas, United States. It is in diameter and the age is estimated to be 58 ± 2 million years (Paleocene). The crater is not exposed at the surface, but some surface formations including the Marquez Dome are thought to be exposed portions of the rebound peak.

Odessa Meteor Crater
The Odessa Meteor Crater is a meteorite crater in the southwestern part of Ector County, southwest of the city of Odessa of West Texas, United States. It is accessible approximately south of Interstate 20 at Exit 108 (Moss Road). This is one of three impact crater sites found in Texas, the others being the older and much larger Sierra Madera crater and the Marquez crater. The ''Handbook of Texas Online'' describes the Odessa meteor crater as the largest of several smaller craters in the immediate area that were formed by the impact of thousands of octahedrites (an iron metallic type) that fell in prehistoric times. The web site of the University of Texas of the Permian Basin (UTPB, Center for Energy and Economic Diversification), identifies five craters at the Odessa site and shows a distribution map of the meteorite fragments recovered from the area. The recoveries have generally come from an area to the north and northwest of the main crater site, with only a few found to the ...

Gene Cernan
Eugene Andrew Cernan (; March 14, 1934 – January 16, 2017) was an American astronaut, naval aviator, electrical engineer, aeronautical engineer, and fighter pilot. During the Apollo 17 mission, Cernan became the eleventh human being to walk on the Moon. As he re-entered the Apollo Lunar Module after Harrison Schmitt on their third and final lunar excursion, he remains as of 2022, famously: "The last man on the Moon". Before becoming an astronaut, Cernan graduated with a Bachelor of Science degree in electrical engineering from Purdue University and joined the U.S. Navy through the Naval Reserve Officers Training Corps (NROTC). After flight training, he received his naval aviator wings and served as a fighter pilot. In 1963, he received a Master of Science degree in aeronautical engineering from the U.S. Naval Postgraduate School. Achieving the rank of captain, he retired from the Navy in 1976. Cernan traveled into space three times and to the Moon twice: as pilot of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Texas
West Texas is a loosely defined region in the U.S. state of Texas, generally encompassing the arid and semiarid lands west of a line drawn between the cities of Wichita Falls, Abilene, and Del Rio. No consensus exists on the boundary between East Texas and West Texas. While most Texans understand these terms, no boundaries are officially recognized and any two individuals are likely to describe the boundaries of these regions differently. Walter Prescott Webb, American historian and geographer, suggested that the 98th meridian separates East and West Texas; Texas writer A.C. Greene proposed that West Texas extends west of the Brazos River. Use of a single line, though, seems to preclude the use of other separators, such as an area— Central Texas. Unlike East Texas, West Texas is not generally considered to be part of the American South, and the dry, desert climate is often more associated with the American Southwest. West Texas is often subdivided according to disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 17
Apollo 17 (December 7–19, 1972) was the final mission of NASA's Apollo program, the most recent time humans have set foot on the Moon or traveled beyond low Earth orbit. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans (astronaut), Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a Fe, Fi, Fo, Fum, and Phooey, biological experiment containing five mice that was carried in the command module. Mission planners had two primary goals in deciding on the landing site: to sample Lunar highlands, lunar highland material older than that at Mare Imbrium and to investigate the possibility of relatively recent Volcano, volcanic activity. They therefore selected Taurus– ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
