<P> While most of the Northeastern United States lie in the Appalachian Highlands physiographic region, some are also part of the Atlantic coastal plain which extends south to the southern tip of Florida . The coastal plain areas (including Cape Cod in Massachusetts, Long Island in New York, most of New Jersey, Delaware, and the Chesapeake Bay region of Maryland) are generally low and flat, with sandy soil and marshy land . The highlands, including the Piedmont and the Appalachian Mountains, are generally heavily forested, ranging from rolling hills to summits greater than 5,000 feet (1,500 m), and pocked with many lakes . The highest peak in the Northeast is Mount Washington (New Hampshire), at 6,288 feet (1,917 m). </P> <P> As of 2007, forest - use covered approximately 60% of the Northeastern states (including Delaware, Maryland, and the District of Columbia), about twice the national average . About 12% was cropland and another 4% grassland pasture or range . There is also more urbanized land in the Northeast (11%) than any other region in the U.S. </P> <P> The climate of the Northeastern United States varies from northernmost Maine to southernmost Maryland . The climate of the region is created by the position of the general west to east flow of weather in the middle latitudes that much of the USA is controlled by and the position and movement of the subtropical highs . Summers are normally warm in northern areas to hot in southern areas . In summer, the building Bermuda High pumps warm and sultry air toward the Northeast, and frequent (but brief) thundershowers are common on hot summer days . In winter the subtropical high retreats southeastward, and the polar jet stream moves south bringing colder air masses from up in Canada and more frequent storm systems to the region . Winter often brings both rain and snow as well as surges of both warm and cold air . </P> <P> The basic climate of the Northeast can be divided into a colder and snowier interior (Pennsylvania and New York State, and New England), and a milder coast and coastal plain from southern Rhode Island southward, including, New Haven, CT, New York City, Philadelphia, Trenton, Wilmington, Baltimore...etc .). Annual mean temperatures range from the low 50s F from Maryland to southern Connecticut, to the 40s F in most of New York State, New England, and northern Pennsylvania . </P>
