Geographic regions of Maryland</div>
</div>
</div>
<p>Maryland is bounded on the north by <a href="/wiki/Pennsylvania" title="Pennsylvania">Pennsylvania</a>, on the west by <a href="/wiki/West_Virginia" title="West Virginia">West Virginia</a>, on the east by <a href="/wiki/Delaware" title="Delaware">Delaware</a> and the Atlantic Ocean, and on the south, across the <a href="/wiki/Potomac_River" title="Potomac River">Potomac River</a>, by <a href="/wiki/West_Virginia" title="West Virginia">West Virginia</a> and <a href="/wiki/Virginia" title="Virginia">Virginia</a>. The mid-portion of this border is interrupted on the Maryland side by <a href="/wiki/Washington,_DC" title="Washington, DC" class="mw-redirect">Washington, DC</a>, which sits on land that was originally part of Maryland. The <a href="/wiki/Chesapeake_Bay" title="Chesapeake Bay">Chesapeake Bay</a> nearly bisects the state, and the counties east of the bay are known collectively as the <a href="/wiki/Eastern_Shore_of_Maryland" title="Eastern Shore of Maryland">Eastern Shore</a>. Most of the state's waterways are part of the Chesapeake Bay watershed, with the exceptions of a portion of <a href="/wiki/Garrett_County,_Maryland" title="Garrett County, Maryland">Garrett County</a> (drained by the <a href="/wiki/Youghiogheny_River" title="Youghiogheny River">Youghiogheny River</a> as part of the watershed of the <a href="/wiki/Mississippi_River" title="Mississippi River">Mississippi River</a>), the eastern half of Worcester County (which drains into Maryland's Atlantic coastal bays), and a small portion of the state's northeast corner (which drains into the <a href="/wiki/Delaware_River" title="Delaware River">Delaware River</a> watershed). So prominent is the Chesapeake in Maryland's geography and economic life that there has been periodic agitation to change the state's official nickname to the "Bay State," a name currently used by <a href="/wiki/Massachusetts" title="Massachusetts">Massachusetts</a>.</p>
<p>The highest point in Maryland is <a href="/wiki/Backbone_Mountain" title="Backbone Mountain">Hoye Crest on Backbone Mountain</a>, in the southwest corner of <a href="/wiki/Garrett_County,_Maryland" title="Garrett County, Maryland">Garrett County</a>, near the border with West Virginia and near the headwaters of the North Branch of the Potomac River. Maryland's only ski area, <a href="/w/index.php?title=Wisp_Resort&action=edit&redlink=1" class="new" title="Wisp Resort (page does not exist)">Wisp</a>, is located close to Backbone Mountain. Close to the small town of <a href="/wiki/Hancock,_Maryland" title="Hancock, Maryland">Hancock</a>, in western Maryland, about two-thirds of the way across the state, the state is only about 1-mile (2 km) wide. This geographical curiosity makes Maryland the narrowest state, bordered by the <a href="/wiki/Mason-Dixon_Line" title="Mason-Dixon Line">Mason-Dixon Line</a> to the north, and the north-arching Potomac River to the south.</p>

</div>
<p>Portions of Maryland are included in various official and unofficial geographic regions. For example, the <a href="/wiki/Delmarva_Peninsula" title="Delmarva Peninsula">Delmarva Peninsula</a> comprises the Eastern Shore counties of Maryland, the entire State of Delaware, and the two counties that make up the <a href="/wiki/Eastern_Shore_of_Virginia" title="Eastern Shore of Virginia">Eastern Shore of Virginia</a>, while the westernmost counties of Maryland are considered part of <a href="/wiki/Appalachia" title="Appalachia">Appalachia</a>. Much of the Baltimore-Washington corridor lies just south of the piedmont in the Coastal Plain,<sup id="cite_ref-11" class="reference"><a href="#cite_note-11" title=""><span>[</span>12<span>]</span></a></sup> though it straddles the border between the two regions.</p>
<p>A quirk of Maryland's geography is that the state contains no natural lakes.<sup id="cite_ref-12" class="reference"><a href="#cite_note-12" title=""><span>[</span>13<span>]</span></a></sup> During the last <a href="/wiki/Ice_Age" title="Ice Age" class="mw-redirect">Ice Age</a>, glaciers did not reach as far south as Maryland, and therefore did not carve out deep natural lakes as exist in northern states. There are numerous man-made lakes, the largest being <a href="/wiki/Deep_Creek_Lake" title="Deep Creek Lake" class="mw-redirect">Deep Creek Lake</a>, a reservoir in <a href="/wiki/Garrett_County" title="Garrett County" class="mw-redirect">Garrett County</a>. The lack of glacial history also accounts for Maryland's soil, which is more sandy and muddy than the rocky soils of <a href="/wiki/New_England" title="New England">New England</a>.</p>

<p>The majority of Maryland's population is concentrated in the cities and suburbs surrounding <a href="/wiki/Washington,_DC" title="Washington, DC" class="mw-redirect">Washington, DC</a> and Maryland's most populous city, <a href="/wiki/Baltimore,_Maryland" title="Baltimore, Maryland" class="mw-redirect">Baltimore</a>. Historically, these and many other Maryland cities developed along the <a href="/wiki/Fall_line" title="Fall line">fall line</a>, the point at which rivers are no longer navigable from sea level due to the presence of rapids or waterfalls. Maryland's capital, <a href="/wiki/Annapolis,_Maryland" title="Annapolis, Maryland">Annapolis</a>, is one exception to this rule, lying along the <a href="/wiki/Severn_River_(Maryland)" title="Severn River (Maryland)">Severn River</a> close to where it empties into the Chesapeake Bay. Other major population centers include suburban hubs <a href="/wiki/Columbia,_Maryland" title="Columbia, Maryland">Columbia</a> in <a href="/wiki/Howard_County,_Maryland" title="Howard County, Maryland">Howard County</a>, <a href="/wiki/Silver_Spring,_Maryland" title="Silver Spring, Maryland">Silver Spring</a>, <a href="/wiki/Rockville,_Maryland" title="Rockville, Maryland">Rockville</a> and <a href="/wiki/Gaithersburg,_Maryland" title="Gaithersburg, Maryland">Gaithersburg</a> in <a href="/wiki/Montgomery_County,_Maryland" title="Montgomery County, Maryland">Montgomery County</a>, <a href="/wiki/Frederick,_Maryland" title="Frederick, Maryland">Frederick</a> in <a href="/wiki/Frederick_County,_Maryland" title="Frederick County, Maryland">Frederick County</a> and <a href="/wiki/Hagerstown,_Maryland" title="Hagerstown, Maryland">Hagerstown</a> in <a href="/wiki/Washington_County,_Maryland" title="Washington County, Maryland">Washington County</a>. The eastern, southern, and western portions of the state tend to be more rural, although they are dotted with cities of regional importance such as <a href="/wiki/Salisbury,_Maryland" title="Salisbury, Maryland">Salisbury</a> and <a href="/wiki/Ocean_City,_Maryland" title="Ocean City, Maryland">Ocean City</a> on the <a href="/wiki/Eastern_Shore_of_Maryland" title="Eastern Shore of Maryland">Eastern Shore</a>, <a href="/wiki/Lexington_Park,_Maryland" title="Lexington Park, Maryland">Lexington Park</a> and <a href="/wiki/Waldorf" title="Waldorf">Waldorf</a> in <a href="/wiki/Southern_Maryland" title="Southern Maryland">Southern Maryland</a>, and <a href="/wiki/Cumberland,_Maryland" title="Cumberland, Maryland">Cumberland</a> in <a href="/wiki/Western_Maryland" title="Western Maryland">Western Maryland</a>.</p>

Some parts of extreme western Maryland possess the cool summer Humid continental climate (Köppen Dfb), with summer average temperatures below 71 °F.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13" title=""><span>[</span>14<span>]</span></a></sup><sup id="cite_ref-14" class="reference"><a href="#cite_note-14" title=""><span>[</span>15<span>]</span></a></sup></p>
<p>Precipitation in the state is very generous, as it is on most of the East Coast. Annual rainfall ranges from 40-45 inches (1000-1150 mm) in virtually every part of the state, falling very evenly. Nearly every part of Maryland receives 3.5-4.5 inches (95-110 mm) per month of precipitation. Snowfall varies from 9 inches (23 cm) in the coastal areas to over 100 inches (250 cm) a winter in the western mountains of the state.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15" title=""><span>[</span>16<span>]</span></a></sup></p>
<p>Because of its location near the <a href="/wiki/Atlantic_Coast" title="Atlantic Coast">Atlantic Coast</a>, Maryland is somewhat vulnerable to <a href="/wiki/Tropical_cyclones" title="Tropical cyclones" class="mw-redirect">tropical cyclones</a>, although the <a href="/wiki/Delmarva_Peninsula" title="Delmarva Peninsula">Delmarva Peninsula</a>, and the outer banks of <a href="/wiki/North_Carolina" title="North Carolina">North Carolina</a> to the south provide a large buffer, such that a strike from a major hurricane (category 3 or above) is not very likely. More often, Maryland might get the remnants of a tropical system which has already come ashore and released most of its energy. Maryland averages around 30-40 days of thunderstorms a year, and averages around 6 tornado strikes annually.<sup id="cite_ref-Annual_average_number_of_tornadoes_16-0" class="reference"><a href="#cite_note-Annual_average_number_of_tornadoes-16" title=""><span>[</span>17<span>]</span></a></sup></p>
