Physiographic regions of the world in the context of "Appalachian Uplands"

The Catskill Mountains, also known as the Catskills, are a physiographic province and subrange of the larger Appalachian Mountains, located in southeastern New York. As a cultural and geographic region, the Catskills are generally defined as those areas close to or within the borders of the Catskill Park, a 700,000-acre (2,800 km) forest preserve protected from many forms of development under New York state law.

Geologically, the Catskills are a mature dissected plateau, a flat region subsequently uplifted and eroded into sharp relief by watercourses. The Catskills form the northeastern end of the Allegheny Plateau (also known as the Appalachian Plateau).

The Maya Block, also known as the Maya Terrane, Yucatan Block, or Yucatan–Chiapas Block, is a physiographic or geomorphic region and tectonic or crustal block in the southernmost portion of the North American Plate.

The Ridge-and-Valley Appalachians, also called the Ridge and Valley Province or the Valley and Ridge Appalachians, are a physiographic province of the larger Appalachian Highlands division. The physiographic province is divided into three sections: the Hudson Valley, the Central, and the Tennessee.

The river valleys were areas of indigenous settlements for thousands of years. In the historic period, the Cherokee people had towns along many of the rivers in western South Carolina and North Carolina, as well as on the western side of the Appalachian Mountains in present-day Tennessee. Similarly, the Catawba people occupied areas along the upper Catawba River in Western North Carolina, to the east of Cherokee County.

Central Texas is a region in the U.S. state of Texas roughly bordered on the west by San Saba, to the southeast by Bryan-College Station, the south by San Marcos and to the north by Hillsboro. Central Texas overlaps with and includes part of the Texas Hill Country and corresponds to a physiographic section designation within the Edwards Plateau, in a geographic context.

Central Texas includes the metropolitan areas of: Killeen-Temple, Bryan–College Station, Waco and Austin–Round Rock (also part of the Capital region). The Austin–Round Rock and Killeen-Temple-Fort Hood areas are among the fastest-growing metropolitan areas in the state. In the south, the Greater Austin and Greater San Antonio areas are separated from each other by approximately 80 miles (129 km) along I-35. It is anticipated that both regions may form a new metroplex similar to Dallas-Fort Worth. The largest U.S. Army installation in the country, Fort Hood, is located near Killeen.
