Montgomery County is a county in the state of Tennessee, USA. It is located in the northern part of the state, right next to the border with Kentucky. As of the 2020 United States census, about 220,069 people lived here.

The main city and county seat of Montgomery County is Clarksville. This is the only official city within the county. Montgomery County was created a long time ago, in 1796. It is part of the larger Clarksville Metropolitan Statistical Area, which includes parts of both Tennessee and Kentucky.

History of Montgomery County

Montgomery County is named after John Montgomery. He was a soldier during the American Revolutionary War and one of the first people to settle in this area. He also helped start the city of Clarksville.

The county was officially formed on April 9, 1796. Before that, this land was part of a larger area called Tennessee County. When Tennessee became a new state, Montgomery County was created. Over the years, the county's size changed a few times, but by 1871, it reached its current borders.

Saltpeter Mining in Montgomery County

Long ago, Montgomery County was important for its saltpeter mines. Saltpeter is a key ingredient used to make gunpowder. People got it by digging up earth from local caves and processing it.

For example, Bellamy Cave near Stringtown still has the remains of many saltpeter processing areas. This shows it was a big operation. Cooper Creek Cave also has signs of a lot of mining. These caves were likely used to get saltpeter during the War of 1812. Dunbar Cave was also used for saltpeter mining around the time of the Mexican War in 1848. However, later building projects have removed most of the evidence there. Mining probably stopped during the Civil War because the Union Army took control of this part of Tennessee early in the war.

Geography of Montgomery County

Montgomery County is located on the northern border of Tennessee, right next to Kentucky. The land here is quite hilly, with many valleys and streams. Most of the county is covered with trees. The Cumberland River flows through the lower central part of the county, winding its way westward.

The highest point in the county is a small hill that is about 806 feet (246 meters) above sea level. This hill is located a few miles east-northeast of Slayden.

The U.S. Census Bureau says that Montgomery County covers a total area of 544 square miles (1,410 square kilometers). Out of this, 539 square miles (1,396 square kilometers) is land, and only 4.7 square miles (12 square kilometers) is water.

Dunbar Cave

Montgomery County has a special type of landscape called karst topography. This means there are many caves and sinkholes underground. A very large cave system in the county is called Dunbar Cave. It is the main feature of Dunbar Cave State Park, which covers about 110 acres. This park is one of the most popular state parks in Tennessee.

Dunbar Cave was used a lot by Native Americans thousands of years ago. They lived in this area for a very long time before Europeans arrived. Inside the cave, researchers have found pieces of their cane torches and many ancient tools and items.

On January 15, 2005, a park ranger and some historians found ancient drawings, called glyphs, on the cave walls. Later, experts confirmed these drawings were made by people of the Mississippian culture, who lived here between 1000 and 1300 CE. These special drawings were shown on cave tours for several years.

In 2010, the State of Tennessee temporarily closed Dunbar Cave to the public. This was because a bat was found with White Nose Syndrome, a serious disease that affects bats. The state wanted to prevent the disease from spreading. The cave has since reopened for tours, which happen seasonally from May to August. Special cleaning rules are in place to keep the bats safe.
