About Flintstone, MD

Nestled in the rugged Appalachian highlands of western Maryland, Flintstone offers residents and visitors a quiet, rural lifestyle surrounded by striking natural scenery. The community is part of the broader Cumberland metropolitan area and reflects the deeply rooted character of western Maryland's mountain communities.
Location & geography
Flintstone is situated in the far western portion of Maryland, roughly 10 to 15 miles southeast of Cumberland, the county seat of Allegany County. The community lies within the Ridge and Valley physiographic province, characterized by long wooded ridges, narrow hollows, and the rolling terrain typical of the Appalachian Mountains. With 60.89 square miles of land area and 0.48 square miles of water area, the region encompasses forested hillsides, small streams, and stretches of rural farmland that define the landscape.
Community & economy
Flintstone is a close-knit rural community where residents value the quiet pace, natural surroundings, and strong sense of local identity common to western Maryland. Agriculture, forestry, and outdoor recreation play important roles in the daily lives of those who call this area home. The community's small scale means that residents often travel to nearby Cumberland or LaVale for major shopping, healthcare, and employment opportunities.
Transportation
Flintstone is accessible primarily via U.S. Route 40, the historic National Road that runs through western Maryland and connects the area to Cumberland to the northwest and Hancock to the southeast. Interstate 68 is also accessible nearby, providing a vital regional corridor through Allegany County and linking Flintstone to the broader interstate highway system. The nearest commercial airport is Eastern WV Regional Airport/Shepherd Field in Martinsburg, West Virginia, though many residents use Hagerstown Regional Airport or Pittsburgh International Airport for more extensive travel options.
History
Flintstone's name is believed to derive from the abundance of flint rock found in the surrounding terrain, a geological characteristic common to the Appalachian ridge-and-valley region. The area developed along the National Road, one of America's first major federally funded highways, which brought early settlers, commerce, and travelers through western Maryland in the nineteenth century. Over the generations, the community transitioned from a waypoint along this important corridor into a quiet residential and agricultural enclave within Allegany County.

Despite its small size, Flintstone shares its distinctive name with the famous animated television franchise, a coincidence that occasionally draws curious visitors looking to photograph the town's signs. The community's expansive land area of over 60 square miles means that Flintstone covers a surprisingly large swath of Allegany County's mountainous western terrain relative to its modest population.
