Somerset County is one of the far southern counties of Pennsylvania, along its straight southern edge. The county borders Garrett and Allegany Counties in Maryland, and the other Pennsylvania counties of Fayette, Westmoreland, Cambria, and Bedford.
Somerset County is one of the snowiest inhabited locations in the United States, with the highest elevations of the county averaging 200+ inches of snow each winter. The county's elevation and proximity to the ocean causes snow from both Nor'easters and lake effect upslope snow events to fall from late October through early April. Snow has been recorded in Somerset County in every month except July, although local lore has it that even July saw snow in 1816, "the year without a summer." Mount Davis, the highest natural point in the state of Pennsylvania at 3,213 feet (979 m), is located in the southern part of the County.

Somerset County is situated along the eastern border of the Allegheny Plateau physiographic province, which is characterized by gently folded to flat-lying sedimentary rocks of middle to late Paleozoic age. The eastern border of the county is approximately at the Allegheny Front, a geological boundary between the Allegheny Plateau and the Ridge and Valley Province (characterized by folded and faulted sedimentary rocks of early to middle Paleozoic age).
The stratigraphic record of sedimentary rocks within the county spans from the Devonian Scherr Formation to the Pennsylvanian Monongahela Formation. Most of these rocks are clastics (conglomerate, sandstone, shale), and there is little or no limestone exposed at the surface. No igneous or metamorphic rocks of any kind exist within the county.
Structurally, Somerset County has many gentle folds, the axes of which trend roughly north-northeast. Synclines include the Youghiogheny Syncline, New Lexington/Johnstown Syncline, Somerset Syncline, Berlin Syncline, and Wellersburg Syncline (called the George's Creek Syncline in Maryland). The southern end of Wilmore Syncline is at the town of Windber. Anticlines include the Laurel Hill Anticline, Centerville Dome, Boswell Dome, Negro Mountain Anticline, and an unnamed anticline between the Berlin and Wellersburg Synclines.
The primary mountains within the county are (from west to east) Laurel Hill (which forms part of the western border), Negro Mountain, Meadow Mountain, Savage Mountain, and Allegheny Mountain. Negro Mountain also includes Mount Davis, the highest peak in Pennsylvania. Each mountain trends northeast.
All of Somerset County lies far to the south of the glacial boundary, and thus it was never glaciated. However, during the Pleistocene epoch (the Ice Age), periglacial processes dominated. Most of the county was most likely a tundra during the Pleistocene. Patterned ground typical of tundra is still visible at Mount Davis, although it is somewhat obscured by vegetation.
The main drainages in southwestern Somerset county are the Casselman River and Laurel Hill Creek which flow into the Youghiogheny River along the southwest border. In the northwest, Stonycreek River, Shade Creek, and Quemahoning Creek (which flows into the Quemahoning Reservoir) are tributaries of the Conemaugh River. All these drainages are part of the Mississippi River Watershed. In the southeast, Wills Creek flows east into Bedford County and then into Maryland where it joins the Potomac River. Also, the headwaters of the Raystown Branch of the Juniata River are to the east of the town of Somerset. Both the Potomac and Juniata rivers are part of the Chesapeake Bay Watershed.
Coal fields exist within Somerset County. The coal is entirely bituminous, and much of it has been mined or is being mined by Strip mining. Most of the coal is within the Main Bituminous Field, which stretched north and west to adjacent counties and southward into Maryland and West Virginia. The rest is within the Georges Creek Field.
There are many abandoned mines in the county, and acid mine drainage is an environmental problem in many areas. Fishless streams exist as a result of the discharge from the abandoned mines. These include parts of the Casselman River, Shade Creek, Stonycreek River, and Quemahoning Creek, as well as many of their tributaries.
Somerset County gained worldwide attention in 2001 when a hijacked airliner, United Airlines Flight 93, crashed in Stonycreek Township near the town of Shanksville in the September 11 Terrorist Attacks. The plane was probably on its way to The Capitol or The White House, but this can not be proved. (See USS Somerset, a U.S. Navy warship which is to be named in commemoration of the Flight 93 tragedy).
The Mountain Playhouse in Jennerstown, Pennsylvania, was one of the nation's first "summer-stock" theaters. The Mountain Playhouse has maintained a full schedule of live theater productions nightly from May through October each year for the last sixty years.
