History

Prior to 1688, the first tract of land in what is now Montgomery County was granted by Charles I in a charter to the first Lord Baltimore (head of the Calvert family). Much later, the creation of Montegomery county became the goal of colonist, Thomas S. Wootton when, on August 31, 1776, he introduced a measure to form a new county from Frederick County, Maryland to aid area residents in simplifying their business affairs. The measure passed, thus creating the new political entity of Montgomery County in the Maryland Colony.

Geography

According to the U.S. Census Bureau, the county has a total area of 507 square miles (1,310 km), of which 491 square miles (1,270 km) is land and 16 square miles (41 km) (3.1%) is water. Montgomery County lies entirely inside the Piedmont plateau. The topography is generally rolling. Elevations range from a low of near sea level along the Potomac River to about 875 feet in the northernmost portion of the county north of Damascus. Relief between valley bottoms and hilltops is several hundred feet.

When Montgomery County was created in 1776, its boundaries were defined as “beginning at the east side of the mouth of Rock Creek on Potowmac river [sic], and running with the said river to the mouth of Monocacy, then with a straight line to Par’s spring, from thence with the lines of the county to the beginning”.

The county’s boundary forms a sliver of land at the far northern tip of the county that is several miles long and averages less than 200 yards wide. In fact, a single house on Lakeview Drive and its yard is sectioned by this sliver into three portions, each separately contained within Montgomery, Frederick and Howard Counties. These jurisdictions and Carroll County meet at a single point at Parr’s Spring on Parr’s Ridge.
