What Canal allows a navigable water route from New York City to the Great Lakes and was created shortly after Blackstone River Valley?
Erie Canal The Erie Canal is a canal in New York that is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal). Originally, it ran 363 mi from Albany, on the Hudson River, to Buffalo, at Lake Erie. It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes. When completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly affected the development and economy of New York, New York City, and the United States.
Wallkill Valley The Wallkill Valley is a broad valley extending through southeastern New York and northwestern New Jersey. It is composed of rolling hills, plains, and swamps (including the Black Dirt Region) surrounding the Wallkill River. The valley is a subdivision of the larger Hudson Valley, bound to the west by the Shawangunk Ridge/Kittatinny Mountains and to the east by the Marlboro Mountains and New York–New Jersey Highlands. The northern Wallkill Valley is sometimes associated with the greater Catskills region, although it is geographically separated from the Catskill Mountains by the Shawangunk Ridge and Rondout Valley. In a broader sense, the Wallkill Valley is part of the Ridge-and-Valley physiographic province of the Appalachian Mountains, while the Catskills further to the north and west are part of the Appalachian Plateau.
