Physiographic regions of the world in the context of Laurentian Highlands

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 Appalachian Uplands is one of the seven physiographic regions in Canada, distinguished by its topography and geology. The region includes southern Quebec, Gaspésie, New Brunswick, Nova Scotia, Prince Edward Island and the island of Newfoundland. This is the Canadian portion of the Appalachian Mountains. The United States equivalent portion is called the Appalachian Highlands.

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.

The Pacific Border province is a physiographic province of the Physiographic regions of the world physical geography system.

The Uinta Basin (also known as the Uintah Basin) is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division. It is also a geologic structural basin in eastern Utah, east of the Wasatch Mountains and south of the Uinta Mountains. The Uinta Basin is fed by creeks and rivers flowing south from the Uinta Mountains. Many of the principal rivers (Strawberry River, Currant Creek, Rock Creek, Lake Fork River, and Uintah River) flow into the Duchesne River which feeds the Green River—a tributary of the Colorado River. The Uinta Mountains form the northern border of the Uinta Basin. They contain the highest point in Utah, Kings Peak, with a summit 13,528 feet (4,123 metres) above sea level. The climate of the Uinta Basin is semi-arid, with occasionally severe winter cold.
