where does harlem begin on the east side
Harlem Harlem is located in Upper Manhattan, often referred to as Uptown by locals. It stretches from the East River in the east, to the Hudson River to the west; and between 155th Street in the north, where it meets Washington Heights, and an uneven boundary along the south that runs along either 96th Street east of Fifth Avenue or 110th Street west of Fifth Avenue.
Appalachian Mountains The Appalachian Mountains[a] (French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion.[4][5] The Appalachian chain is a barrier to east-west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east-west.
