In 1787, theNorth Carolina legislature ordered widening and improvements toAvery's Trace, the trail that ran from North Carolina throughKnoxville and what is now Cumberland County toNashville. They raised funds by a lottery and completed a project that built a wagon road. This slightly improved travel, but still required a bone jarring trip. The road was often muddy and crossed stone slabs so that it was only passable in some places on foot. Reportedly wagons could not get down the steep grade at Spencer's Mountain without locking brakes on all wheels and dragging a tree behind to slow the descent. The mountain top was described as "quite denuded of trees."

Cumberland County was the site of an importantsaltpeter mine. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from Grassy Cove Saltpeter Cave. Richard Green Waterhouse settled in this area in 1800. In his "Diary, Journal, and Memoirs" he states that he went with William Kelly into Grassy cove and explored his (Kelly's) saltpeter cave on October 7, 1812.[7]
According to Barr (1961), Dicky Mathews began the manufacture of gunpowder at the cave in 1859. His son was killed by an explosion at Powder House Spring below the cave. This is an exceptionally large cave and evidence of mining extends far from the entrance. The leaching vats were located in a large room near the entrance, but this room is damp and the wooden vats have deteriorated to the point that they are difficult to recognize.[8]
During the 1930s, as part of theNew Deal, the federal government'sSubsistence Homesteads Division established theCumberland Homesteads outside of Crossville. The program provided land and houses for 250 impoverished families. Cumberland Mountain State Park was built as part of this project.[6]
According to theU.S. Census Bureau, the county has a total area of 685 square miles (1,770 km2), of which 681 square miles (1,760 km2) is land and 3.8 square miles (9.8 km2) (0.6%) is water.[9] It is the fourth-largest county in Tennessee by area. The county is located atop theCumberland Plateau. The southernmost of theCumberland Mountains, known locally as theCrab Orchard Mountains, rise in the northeastern part of the county.
The county is home to a number ofkarst formations, most notably atGrassy Cove, a large, closed depression located southeast of Crossville. It is 3 miles wide, 5 miles long, and over 1,000 feet deep. All of the water draining into Grassy Cove flows underground through a large cave system and emerges 4 miles southwest at the head of theSequatchie Valley to form theSequatchie River.
The Tennessee Divide, where the watersheds of theCumberland River and theTennessee River meet, passes through the county. The source of theCaney Fork is located west of the divide, while the source of theObed River is located east of the divide.

Like all ofEast Tennessee, Cumberland County is powerfully Republican, and has generally been favorable to the party sincethe Civil War. Five Democratic presidential candidates have won the county since then, but none have reached 52 percent of the county's vote. For example,Franklin Roosevelt andLyndon Johnson only won the county by fewer than 100 votes even as they won over 40 states and 400 electoral votes. The Democrats have only managed 40 percent of the county's vote five other times.
