Bat Cave Hollow is a valley in eastern Oregon County in the Ozarks of southern Missouri. [1]
A valley is a low area between hills or mountains typically with a river running through it. In geology, a valley or dale is a depression that is longer than it is wide. The terms U-shaped and V-shaped are descriptive terms of geography to characterize the form of valleys. Most valleys belong to one of these two main types or a mixture of them, at least with respect to the cross section of the slopes or hillsides.
Oregon County is a county located in the southern portion of the U.S. state of Missouri. As of the 2010 census, the population was 10,881. Its county seat is Alton. The county was officially organized on February 14, 1845, and was named for the Oregon Territory in the northwestern United States.
The Ozarks, also called the Ozark Mountains or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, Oklahoma, and extreme southeastern Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in Arkansas to Interstate 70 in central Missouri.
The intermittent stream in Bat Cave Hollow [2] has headwaters at 36°42′36″N91°17′13″W / 36.71000°N 91.28694°W and its confluence with the Eleven Point River is at 36°40′59″N91°11′50″W / 36.68306°N 91.19722°W Coordinates: 36°40′59″N91°11′50″W / 36.68306°N 91.19722°W . [1]
In geography, a confluence occurs where two or more flowing bodies of water join together to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river ; or where two streams meet to become the source of a river of a new name ; or where two separated channels of a river rejoin at the downstream end.
The Eleven Point River is a 138-mile-long (222 km) river in southern Missouri and northern Arkansas, United States. It originates near Willow Springs, Missouri. It more than doubles in flow when Greer Spring Branch runs into it, adding over 200 million US gallons (760,000 m3) of water per day to the river. The name derives from the Mississippi Valley French word pointe, which is a wooded point of land marking a river bend. Voyageurs marked distance by counting these points of land or river bends. The river flows into the Spring River southwest of Pocahontas near the small town of Black Rock.
A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
Bat Cave Hollow was named for Bat Cave which lies on the south bank of the stream [2] and hosted a bat colony. [3]
Bats are mammals of the order Chiroptera; with their forelimbs adapted as wings, they are the only mammals naturally capable of true and sustained flight. Bats are more manoeuvrable than birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is 29–34 mm (1.14–1.34 in) in length, 15 cm (5.91 in) across the wings and 2–2.6 g (0.07–0.09 oz) in mass. The largest bats are the flying foxes and the giant golden-crowned flying fox, Acerodon jubatus, which can weigh 1.6 kg (4 lb) and have a wingspan of 1.7 m.
