Mesa
A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain. Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock, e.g. shales overlain by sandstones. The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike ''plateau'', whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term ''mesa'' applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as '' tablelands''.Duszyński, F., Migoń, P. and Strzelecki, M.C., 2019.

Navajo Language
Navajo or Navaho (; Navajo: or ) is a Southern Athabaskan language of the Na-Dené family, through which it is related to languages spoken across the western areas of North America. Navajo is spoken primarily in the Southwestern United States, especially on the Navajo Nation. It is one of the most widely spoken Native American languages and is the most widely spoken north of the Mexico–United States border, with almost 170,000 Americans speaking Navajo at home as of 2011. The language has struggled to keep a healthy speaker base, although this problem has been alleviated to some extent by extensive education programs in the Navajo Nation, including the creation of versions of the films Finding Nemo and Star Wars dubbed into Navajo. The United States in World War II used the Navajo language to develop a system of code talkers to relay messages that could not be cracked. Navajo has a fairly large phoneme inventory, including several uncommon consonants that are not found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Mary (Arizona)
Lake Mary may refer to one of two reservoirs in northern Arizona southeast of Flagstaff. The name may also be used to refer to the two lakes as a whole. The pair of lakes impound the intermittent Walnut Creek upstream from Walnut Canyon. Recreational facilities at both lakes are maintained under the authority of the Coconino National Forest. Upper Lake Mary Upper Lake Mary, the furthest upstream of the two lakes, is formed by a small earthen dam on Walnut Creek. In 1941, the city of Flagstaff built a second dam south of Lake Mary, creating Upper Lake Mary. The lake is long and narrow, with a maximum length of about , and a maximum width of about . During dry seasons the lake will narrow and shorten. Upper Lake Mary contains nine fish species for angling, including black crappie, bluegill, green sunfish, channel catfish, northern pike and walleye. Largemouth bass, yellow bass and yellow perch are sometimes reported to be found in the lake as well. Also golden shiners and f ...

Mormon Lake
Mormon Lake is a shallow, intermittent lake located in northern Arizona in Pleasant Valley. With an average depth of only , the surface area of the lake is extremely volatile and fluctuates seasonally. When full, the lake has a surface area of about , making it the largest natural lake in Arizona. In particularly dry times, the lake has been known to dry up, leaving behind a remnant marsh. The surrounding area, which lies within Coconino National Forest, established in 1908, is part of the largest continuous stand of ponderosa pine in North America, often hosting campers and hikers. The lake itself is occasionally stocked with fish species such as bullhead catfish and northern pike, but due to its intermittent nature, it may contain few or no fish following dry seasons. The name of the lake commemorates Mormon settlers who migrated to northern Arizona in the 1870s. The settlers, who located their main communities along the Little Colorado River, established various cottage i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landform
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowell Observatory
Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States. Lowell Observatory was established in 1894, placing it among the oldest observatories in the United States, and was designated a National Historic Landmark in 1965. and In 2011, the Observatory was named one of "The World's 100 Most Important Places" by Time Magazine. It was at the Lowell Observatory that the dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh. The observatory was founded by astronomer Percival Lowell of Boston's Lowell family and is overseen by a sole trustee, a position historically handed down through the family. The first trustee was Lowell's third cousin Guy Lowell (1916–1927).
