Garrett County is the westernmost county of the U.S. state of Maryland completely within the Appalachian Mountains. As of the 2020 census, the population was 28,806, making it the third-least populous county in Maryland. Its county seat is Oakland. The county was named for John Work Garrett (1820–1884), president of the Baltimore and Ohio Railroad. Created from Allegany County in 1872, it was the last county to be formed in the state.
The Eastern Continental Divide, Eastern Divide or Appalachian Divide is a hydrological divide in eastern North America that separates the easterly Atlantic Seaboard watershed from the westerly Gulf of Mexico watershed. The divide nearly spans the United States from south of Lake Ontario through the Florida peninsula, and consists of raised terrain including the Appalachian Mountains to the north, the southern Piedmont Plateau and lowland ridges in the Atlantic Coastal Plain to the south. Water including rainfall and snowfall, lakes, streams and rivers on the eastern/southern side of the divide drains to the Atlantic Ocean; water on the western/northern side of the divide drains to the Gulf of Mexico. The ECD is one of six continental hydrological divides of North America which define several drainage basins, each of which drains to a particular body of water.
The Youghiogheny River, or the Yough for short, is a 134-mile-long (216 km) tributary of the Monongahela River in West Virginia, Maryland, and Pennsylvania. It drains an area on the west side of the Allegheny Mountains northward into Pennsylvania, providing a small watershed in extreme western Maryland into the tributaries of the Mississippi River. Youghiogheny is a Lenape word meaning "a stream flowing in a contrary direction".
Backbone Mountain is a ridge of the Allegheny Mountains of the central Appalachian Mountain Range. It is situated in the U.S. states of West Virginia and Maryland and forms a portion of the Eastern Continental Divide. Within the state of Maryland, Backbone Mountain reaches an elevation of 3,360 feet or 1,024 metres, making it Maryland's highest point.
The Allegheny Front is the major southeast- or east-facing escarpment in the Allegheny Mountains in southern Pennsylvania, western Maryland, eastern West Virginia, and western Virginia. The Allegheny Front forms the boundary between the Ridge-and-Valley Appalachians to its east and the Appalachian Plateau to its west. The Front is closely associated with the Appalachian Mountains' Eastern Continental Divide, which in this area divides the waters of the Ohio/Mississippi river system, flowing to the Gulf of Mexico, from rivers flowing into Chesapeake Bay and from there into the Atlantic Ocean.
Rock Creek is a tributary of the Potomac River, in the United States, that empties into the Atlantic Ocean via the Chesapeake Bay. The 32.6-mile (52.5 km) creek drains about 76.5 square miles (198 km2). Its final quarter-mile is affected by tides.
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern.
Maryland Route 135 is a state highway in the U.S. state of Maryland. Known for most of its length as Maryland Highway, the state highway runs 29.00 miles (46.67 km) from U.S. Route 219 in Oakland in Garrett County east to US 220 in McCoole in Allegany County. MD 135 is the main link between the towns of Oakland, Mountain Lake Park, Loch Lynn Heights, and Deer Park on the Appalachian Plateau and the communities of Bloomington, Luke, Westernport, and McCoole in the upper valley of the North Branch Potomac River. These groups of towns are separated by Backbone Mountain.
Ohiopyle State Park is a Pennsylvania state park on 20,500 acres (8,300 ha) in Dunbar, Henry Clay and Stewart Townships, Fayette County, Pennsylvania in the United States. The focal point of the park is the more than 14 miles (23 km) of the Youghiogheny River gorge that passes through the park. The river provides whitewater boating, recreational fishing, and kayaking. Ohiopyle State Park is bisected by Pennsylvania Route 381 south of the Pennsylvania Turnpike. The park opened to the public in 1965 but was not officially dedicated until 1971.
Swallow Falls State Park is a public recreation area located on the west bank of the Youghiogheny River nine miles (14 km) northwest of Oakland in Garrett County, Maryland, in the United States. The state park features Maryland's highest free-falling waterfall, the 53-foot (16 m) Muddy Creek Falls, as well as smaller waterfalls on the Youghiogheny River and Tolivar Creek. The park is notable for its stand of old hemlock trees, some more than 300 years old, "the last stand of its kind in Maryland."
The Casselman River is a 56.5-mile-long (90.9 km) tributary of the Youghiogheny River in western Maryland and Pennsylvania in the United States. The Casselman River drains an area of 576 square miles.
Maryland Route 39 is a state highway in the U.S. state of Maryland. Known for much of its length as Hutton Road, the state highway begins at the West Virginia state line in Hutton, where the highway continues west as West Virginia Route 7. MD 39, which is the westernmost state-numbered highway in Maryland, runs 6.22 miles (10.01 km) from Hutton east through Crellin to U.S. Route 219 in Oakland. The state highway was constructed in the early 1920s.
The Youghiogheny River Lake is a flood control reservoir that is located in southwestern Pennsylvania and western Maryland. It is a significant tourist attraction that brings in more than one million visitors a year to the area.
Maryland Route 38 is a state highway in the U.S. state of Maryland. Known as Kitzmiller Road, the state highway runs 5.67 miles (9.12 km) from the West Virginia state line at the North Branch Potomac River in Kitzmiller, where the highway continues south as West Virginia Route 42, north to MD 135 on top of Backbone Mountain. MD 38 connects Kitzmiller with the rest of Garrett County and across the North Branch Potomac River to Blaine and Elk Garden in western Mineral County. The state highway was constructed in the late 1920s and early 1930s. MD 38 originally ran from U.S. Route 219 near Thayerville through Deer Park and Altamont to Kitzmiller. The state highway was truncated at Backbone Mountain when MD 135 was extended west to Oakland in the mid-1950s.
Maryland Route 495 is a state highway in the U.S. state of Maryland. Known for most of its length as Bittinger Road, the state highway runs 23.02 miles (37.05 km) from MD 135 in Altamont north to U.S. Route 40 Alternate in Grantsville. MD 495 passes through rural areas of central Garrett County, connecting Bittinger with the northern and southern parts of the county. The state highway also provides an alternate route to US 219 between Interstate 68 (I-68) and resorts around Deep Creek Lake. MD 495 was constructed from both ends starting in the mid-1930s. By the late 1940s, the state highway was complete except for a 5 miles (8.0 km) gap south of Bittinger; this gap was filled in the mid-1950s. The southern terminus of MD 495 was extended to Altamont in 1956.
Savage River State Forest is located in the north and northeastern part of Garrett County, in the U.S. state of Maryland. The state forest has many waterways, including Savage River Reservoir, which was built in 1952 by the U.S. Army. The dam was built as an emergency water supply for Washington, D.C. Savage River State Forest is known for its hunting, fishing, camping, and hiking trails.
Tuscarora Creek is a 7.7-mile-long (12.4 km) tributary of the Monocacy River in Frederick County, Maryland, in the United States.
Bread and Cheese Creek is a tributary of the Back River in Baltimore County, Maryland. The creek is 3.2 miles (5.1 km) long, with headwaters just east of the Baltimore city line. It flows east through Baltimore County before emptying into the Back River, which flows into the Chesapeake Bay. The watershed area of the creek is 1.85 square miles (4.8 km2).
Blair Gap, one of the gaps of the Allegheny, is a water gap along the eastern face atop the Allegheny Front escarpment. Like other gaps of the Allegheny, the slopes of Blair Gap were amenable to foot travel, pack mules, and possibly wagons allowing Amerindians, and then, after about 1778–1780 settlers, to travel west into the relatively depopulated Ohio Country decades before the railroads were born and tied the country together with steel.
The gaps of the Allegheny, meaning gaps in the Allegheny Ridge in west-central Pennsylvania, is a series of escarpment eroding water gaps along the saddle between two higher barrier ridge-lines in the eastern face atop the Allegheny Ridge or Allegheny Front escarpment. The front extends south through Western Maryland and forms much of the border between Virginia and West Virginia, in part explaining the difference in cultures between those two post-Civil War states. While not totally impenetrable to daring and energetic travelers on foot, passing the front outside of the water gaps with even sure footed mules was nearly impossible without navigating terrain where climbing was necessary on slopes even burros would find extremely difficult.
