Southern Indiana

Southern Indiana is a region consisting of the southern third of the state of Indiana.

Indiana State of the United States of America

Indiana is a U.S. state located in the Midwestern and Great Lakes regions of North America. Indiana is the 38th largest by area and the 17th most populous of the 50 United States. Its capital and largest city is Indianapolis. Indiana was admitted to the United States as the 19th U.S. state on December 11, 1816. Indiana borders Lake Michigan to the northwest, Michigan to the north, Ohio to the east, Kentucky to the south and southeast, and Illinois to the west.

Weed Patch Hill third-highest summit in Indiana, United States

Weed Patch Hill, also known as Weed Patch Knob, is the third highest named summit in the U.S. state of Indiana. Located in Washington Township and Brown County State Park, it is the highest point in the Knobstone Escarpment.

The escarpment's most prominent feature is its steep hills, often called "knobs", and ravines. Brown County State Park features views from the region's highest elevations.

This bold ridge, towering hundreds of feet above the Scottsburg Lowland to the east, extends from southern Johnson County 150 miles southward across the Ohio River into Kentucky. These scenic hills mark the easternmost extension of rocks forming the rugged country of the Norman Upland to the west. The Hills of Brown County are a well-known example of Norman Upland topography. [1]

The Knobstone Escarpment is composed of resistant siltstones of the upper part of Borden Group rocks. Older and more easily eroded shales to the east form the Scottsburg Lowland; a thick section of soluble limestones form the undulating Mitchell Plain west of the Norman Upland.

Great Dividing Range mountain range in the Australian states of Queensland, New South Wales and Victoria

The Great Dividing Range, or the Eastern Highlands, is Australia's most substantial mountain range and the third longest land-based range in the world. It stretches more than 3,500 kilometres (2,175 mi) from Dauan Island off the northeastern tip of Queensland, running the entire length of the eastern coastline through New South Wales, then into Victoria and turning west, before finally fading into the central plain at the Grampians in western Victoria. The width of the range varies from about 160 km (100 mi) to over 300 km (190 mi). The Greater Blue Mountains Area, Gondwana Rainforests, and Wet Tropics of Queensland World Heritage Areas are located in the range.

Missouri, a state near the geographical center of the United States, has three distinct physiographic divisions:

Escarpment Steep slope or cliff separating two relatively level regions

An escarpment, or scarp, is a steep slope or long cliff that forms as an effect of faulting or erosion and separates two relatively level areas having differing elevations. Usually scarp and scarp face are used interchangeably with escarpment.

Drakensberg mountain range in South Africa

The Drakensberg is the name given to the eastern portion of the Great Escarpment, which encloses the central Southern African plateau. The Great Escarpment reaches its greatest elevation in this region – 2,000 to 3,482 metres. It is located in South Africa and Lesotho.

Allegheny Front

The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, and eastern West Virginia, USA. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.

Western Upland

The Western Upland is a geographical region covering much of the western half of the U.S. state of Wisconsin. It stretches from southern Polk County, Wisconsin in the north to the state border with Illinois in the south, and from Rock County in the east to the Mississippi River in the west.

Eastern Ridges and Lowlands

The Eastern Ridges and Lowlands is a geographical region in the eastern part of the U.S. state of Wisconsin, between Green Bay in the north, and the border with Illinois in the south. Lake Michigan lies to the east of the region.

Geography of Illinois

Illinois is in the midwestern United States. Surrounding states are Wisconsin to the north, Iowa and Missouri to the west, Kentucky to the south, and Indiana to the east. Illinois also borders Michigan, but only via a northeastern water boundary in Lake Michigan. Nearly the entire western boundary is the Mississippi River, except for a few areas where the river has changed course. Illinois' southeastern and southern boundary is along the Wabash River and the Ohio River. Whereas, its northern boundary and much of its eastern boundary are straight survey lines. Illinois has a maximum north-south distance of 390 miles and 210 miles east-west. Its total area is 57,918 square miles (150,010 km2).

Floyds Knobs, Indiana Unincorporated community in Indiana, United States

Floyds Knobs is a small unincorporated community in Lafayette Township, Floyd County, Indiana, United States. Historically a farming community on the outskirts of New Albany, it has since become a bedroom community for Louisville, Kentucky.

The Indiana Uplands are a geographical region in south-central Indiana. On a topographical map the Indiana Uplands begin slightly north of the city of Martinsville, Indiana and continue south to the Ohio River. The description of the region inspired the name of Upland Brewing Company. The region's approximate boundaries are Interstate 65 to the east and U.S. Route 231 to the west. The Uplands are characterized by rolling hills composed of sandstone, limestone, and siltstone from West to east. The siltstone hills are the most rugged followed by the sandstone while the limestone are the smoothest. This is contrast to the Tipton Till Plain immediately to the north in central Indiana, which features flat to gently rolling landscape.

Hoosier Hill mountain

Hoosier Hill is the highest natural point in the state of Indiana at 1,257 feet (383 m) above sea level. It is in the rural area of Franklin Township, Wayne County to the northwest of Bethel. The nearest intersection to the high point is Elliot Road and County Line Road. The nearest major landmark is Interstate 70 and Richmond 11 miles (17.5 km) to the south.

Cody Scarp

The Cody Scarp or Cody Escarpment is located in north and north central Florida United States. It is a relict scarp and ancient persistent topographical feature formed from an ancient early Pleistocene shorelines of ~1.8 million to 10,000 years BP during interglacial periods. The Cody Scarp has a slope of 5% to 12%.

Great Escarpment, Southern Africa Major topographical feature in southern Africa

The Great Escarpment is a major topographical feature in Africa that consists of steep slopes from the high central Southern African plateau downward in the direction of the oceans that surround Southern Africa on three sides. While it lies predominantly within the borders of South Africa, in the east it extends northwards to form the border between Mozambique and Zimbabwe, continuing on beyond the Zambezi River valley to form the Muchinga Escarpment in eastern Zambia. In the west, it continues northwards into Namibia and Angola.

The Knobstone Trail is the longest hiking trail in Indiana. Its southern terminus is about 15 miles (24 km) north of Louisville, Kentucky in the Deam Lake State Recreation Area. It currently ends at Delaney Creek Park near Salem, Indiana. However, there are plans to eventually extend the trail another 80 miles (129 km) north to Martinsville, Indiana. Most of the trail lies within Clark State Forest. As it lies along the Knobstone Escarpment, it is a difficult hike, which is why many use the Knobstone Trail to prepare for hiking the Appalachian Trail.

Greensand Ridge sandstone escarpment and range of hills in south-east England

The Greensand Ridge is an extensive, prominent, often wooded, mixed greensand/sandstone escarpment in south-east England. It runs to and from the East Sussex coast, around the Weald, a former dense forest in Sussex, Surrey and Kent. It reaches its highest elevation, 294 metres (965 ft), at Leith Hill in Surrey—the second highest point in south-east England, while another hill in its range, Blackdown, is the highest point in Sussex at 280 metres (919 ft). The eastern end of the ridge forms the northern boundary of Romney Marsh.

Geology of Pennsylvania

Geographic coordinate system Coordinate system

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.
