Rockbridge State Nature Preserve
Rockbridge State Nature Preserve is a nature reserve featuring a natural bridge located in the unincorporated community of Rockbridge in Hocking County, Ohio, United States. It is part of the Hocking Hills region, but the sandstone that forms the natural bridge is located lower in the stratigraphic sequence than that which forms most of the region's notable features. Nature preserve The preserve consists of of land which borders the Hocking River and is connected to the trailhead via a narrow easement. The park's trail system includes two loop trails, one of which passes the natural bridge, while the other passes a rock shelter. Both formations are located a short distance from the Hocking River on small tributaries. The preserve was acquired by the state of Ohio in 1978. Natural bridge The natural bridge is the largest of at least 12 natural bridges in the state of Ohio. It is approximately long, wide, and thick. It was formed when water eroded the softer layers of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stratigraphy
Stratigraphy is a branch of geology concerned with the study of rock layers ( strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of strata or rock layering and the importance of fossil markers for correlating strata; he created the first geol ...

Landforms Of Hocking County, Ohio
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.

Protected Areas Of Hocking County, Ohio
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Natural Arches Of Ohio
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-So ...

Mississippian (geology)
The Mississippian ( , also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land. The cratons were surrounded by extensive delta systems and lagoons, and carbonate sedimentation on the surrounding continental platforms, covered by shallow seas. In North America, where the interval consists primarily of marine limestones, it is t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Shelter
A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves (karst), which are often many miles long, rock shelters are almost always modest in size and extent. Formation Rock shelters form because a rock stratum such as sandstone that is resistant to erosion and weathering has formed a cliff or bluff, but a softer stratum, more subject to erosion and weathering, lies just below the resistant stratum, and thus undercuts the cliff. In arid areas, wind erosion (Aeolian erosion) can be an important factor in rockhouse formation. In most humid areas, the most important factor in rockhouse formation is frost spalling, where the softer, more porous rock underneath is pushed off, tiny pieces at a time, by frost expansion from water frozen in the pores. Erosion from moving water is seldom a significant factor. Many rock shelters are found under waterfalls. File:Rock sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hocking River
The Hocking River (formerly the Hockhocking River) is a right tributary of the Ohio River in southeastern Ohio in the United States. The Hocking flows mostly on the unglaciated Allegheny Plateau, but its headwaters are in a glaciated region. It rises in Bloom Township in Fairfield County and flows generally southeastwardly through Fairfield, Hocking, and Athens counties, through the Hocking Hills region and past the cities of Lancaster, Logan, Nelsonville, Athens and Coolville. It joins the Ohio River at Hockingport. The Hocking's tributaries also drain parts of Perry, Morgan, and Washington Counties. Its name originally derives from a Native American name, roughly "Hokhokken" or "Hokhochen", which meant "bottle-shaped" or "gourd-shaped" and referred to the river's headwaters 7 miles north-west of present-day Lancaster, Ohio. The river begins as a small stream, then immediately goes over a waterfall into a wide gorge. When viewed from above this feature looks like ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hocking County, Ohio
Hocking County is a county located in the U.S. state of Ohio. As of the 2020 census, the population was 28,050. Its county seat is Logan. The county was organized on March 1, 1818, from land given by Athens, Fairfield, and Ross counties.

Hocking Hills
The Hocking Hills is a deeply dissected area of the Allegheny Plateau in Ohio, primarily in Hocking County, that features cliffs, gorges, rock shelters, and waterfalls. The relatively extreme topography in this area is due to the Blackhand Sandstone (so named because of Native American graphics on the formation near Newark, Ohio), a particular formation that is thick, hard and weather-resistant, and so forms high cliffs and narrow, deep gorges. Component open-space areas Most of the more scenic areas of the region are under state ownership, including: * Hocking Hills State Park (with five use areas: Ash Cave, Cedar Falls, Old Man's Cave, Rockhouse, and Cantwell Cliffs) *Hocking State Forest *Conkle's Hollow State Nature Preserve *Sheick Hollow State Nature Preserve (entry by permit only) *Little Rocky Hollow State Nature Preserve (entry by permit only) * Kessler Swamp State Nature Preserve * Lake Logan State Park *Wayne National Forest *Rockbridge State Nature Preserve The cor ...
