Head of navigation in the context of "Fort Western"

A fall line (or fall zone) is the area where an upland region and a coastal plain meet and is especially noticeable at the place rivers cross it, with resulting rapids or waterfalls. The uplands are relatively hard crystalline basement rock, and the coastal plain is softer sedimentary rock. A fall line often will recede upstream as a river cuts out the uphill dense material, forming "c"-shaped waterfalls and exposing bedrock shoals. Due to these features, riverboats typically cannot travel any further inland without portaging, unless locks are built. The rapid change of elevation of the water and resulting energy release make the fall line a good location for water mills, grist mills, and sawmills. Seeking a head of navigation with a ready supply of water power, people have long made settlements where rivers cross a fall line.

Hit or Heet (Arabic: هيت, Hīt) is a city in Al Anbar Governorate of Iraq. Situated on the banks of the Euphrates River, it lies northwest of Ramadi, the provincial capital. The city is administrative capital for Hit District. A major city in the central region, it has a population over 100,000.

Straddling the Euphrates, the city of Hit was originally a small walled town surrounded by a halt moat and built on two mounds on the site of the ancient city of Is. In ancient times, the town was known for its bitumen wells; bitumen from the wells was used in the construction of Babylon over 3000 years ago, and for tasks such as caulking boats. Hit also became a frontier fortress for Assyria. Now, Hit is a marketplace for agricultural produce. Oil pipelines to the Mediterranean Sea cross the Euphrates there. It was regarded as the head of navigation on the river before the decline in river traffic.

Allen's Landing is the officially recognized birthplace of the city of Houston, Texas, United States, the largest city in Texas and the fourth largest in the United States. Located in Downtown Houston between the Main Street and Fannin Street viaducts, the landing encompasses the southern bank of Buffalo Bayou, the city's principal river, at its confluence with White Oak Bayou, a major tributary. Allen's Landing is located south of the University of Houston–Downtown Commerce Street Building.

In August 1836, just months after the Republic of Texas won its independence from Mexico, two New York real estate developers, John Kirby Allen and Augustus Chapman Allen, purchased 6,642 acres (26.88 km) of coastal prairie and settled the town of Houston on the banks of Buffalo Bayou. The present-day landing area was advertised as the head of navigation of the bayou and served as the city's first wharf.

Kisangani (/kiːsəŋˈɡɑːni/), formerly Stanleyville (Dutch: Stanleystad), is the capital of Tshopo Province, located on the Congo River in the eastern part of the central Congo Basin in the Democratic Republic of the Congo. It is the country's fifth-most populous urban area, with an estimated population of 1,602,144 as of 2016, and the largest of the cities in the tropical woodlands of the Congo.

Geographically, Kisangani is flanked by Banalia Territory to the north, Bafwasende to the east, Ubundu Territory to the south, and is bordered by both Opala and Isangi Territories to the west. The city spans an area of 1,910 square kilometers and is situated within the equatorial forest plain at coordinates 0°30' north latitude and 25°20' east longitude, just 80 kilometers from the equator. Kisangani is located approximately 2,100 kilometers (1,300 miles) from the mouth of the Congo River, making it the farthest navigable point upstream.

Elkton is a town in and the county seat of Cecil County, Maryland, United States. The population was 15,776 at the 2020 census, up from 15,443 in 2010. It was formerly called Head of Elk because it sits at the head of navigation on the Elk River, one of the five tributary rivers that flow into the north of the Chesapeake Bay, east of the Susquehanna River and North East River, and north of the Bohemia River, and Sassafras River.
