Mark Twain National Forest

Mark Twain National Forest is a large area of federally managed land located in the central and southern parts of the US state of Missouri. The expansive forest consists of a number of sections that include land throughout the southern half of the state. Mark Twain National Forest contains 203 named mountains, the tallest of which is Bell Mountain at 1,703 ft (519 m) and the most prominent of which is Matthews Mountain with 554 ft (169 m) of prominence.

Mark Twain National Forest


Mark Twain National Forest is situated in southern Missouri and is broken down into numerous subdistricts. The forest spans 1.5 million acres (607,000 ha). The protected land encompasses over 10% of the state’s forested land.

The forest is broken up into 11 land units that are managed as part of 6 ranger districts. Despite its relatively small size when compared to national forests in the western United States, the Mark Twain National Forest is located in 30 counties, which is substantially more than any other forest.

Large amounts of the landscape in the Mark Twain National Forest are dominated by densely forested rolling hills. As such, elevation changes are generally quite mild within the forest.

One of the defining features of the forest is Greer Spring. The spring is the largest within a national forest and it has a daily flow of over 200 million U.S. gallons (757 million liters). There are a number of other rivers that run throughout the forest, providing the region with plenty of swimming holes for visitors to check out.

There are seven designated wilderness areas throughout the forest which also happen to be the only seven wilderness areas within the entire state. These include:

Additionally, Mark Twain National Forest is surrounded by other popular outdoor recreation areas. To the south, in Arkansas, lie both Ozark-St. Francis National Forest and Ouachita National Forest. Meanwhile, the forest is located within driving distance of the Ozark National Scenic Riverways, which is situated to the north in Missouri.


The geological history of the Ozarks region is unique and varied. Millions of years ago, when the South America plate came into contact with the North American plate, the land that is now the Ozark Plateau was thrust upward.

Soluble rocks formed much of the now-raised land mass. Over time, the deep erosion of this portion of land left behind karst formations. Today the forest is home to various springs, streams, caves, and sinkholes.

Because of this abundance of karst formations, Missouri is known as the “Cave State,” with over 7,000 caves having been recorded in the region alone. There are thousands of springs throughout the forest whose waters have carved out the land over millions of years.

Beneath the forest’s floor lies large deposits of zinc, lead, and copper ore. As a result, there is a long history of mining in the region.

Major peaks within the forest include Bell Mountain, Matthews Mountain, Lindsey Mountain, Marlow Mountain, Johnson Mountain, and Grassy Mountain.

Autumn Mark Twain National Forest


Mark Twain National Forest is home to a vast amount of biodiversity. The eastern stretches of the forest are home to predominantly oak forests while the southern stretches are dominated by pine trees.

Other species of trees include hickories, yellow poplar, flowering dogwood, and sugar maple. Wildflowers are also abundant throughout the region during the summer months.

The forest is home to over 300 species of birds and 75 species of mammals. Common animals within the forest boundaries include wild turkey, whitetail deer, opossums, rabbits, raccoons, ducks, geese, bobcats, and coyotes.

While seeing a black bear is uncommon, they do occasionally enter the national forest. Feral hogs are also found throughout the entire forest.

Human History

The Mark Twain National Forest was inhabited for thousands of years prior to the arrival of Europeans. People of the Mississippian culture are believed to have lived in the region as early as about 9,000 BCE.

There are currently no federally-recognized tribes within Missouri. However, before the arrival of European and European-American settlers, the region was home to a number of Indigneous communities. Many tribal nations that are headquartered outside of what is now Missouri have traditional ties to the region, including the Quapaw Nation, Osage Nation, Otoe-Missouria Tribe, Shawnee Tribe, Chickasaw Nation, and the Sac & Fox Nation.

The first peoples of European descent to have visited what is now the Mark Twain National Forests were likely French and French-Canadian fur traders who arrived in the late seventeenth century. The region was then claimed by France until it was ceded to Spain as part of the Treaty of Fontainebleau. It was soon returned to France and then sold to the US as part of the Louisiana Purchase.

During the 1870s, extensive logging took place throughout much of southern Missouri. Over the course of 50 years, overlogging had taken its toll on the land and destroyed much of the region’s native forests.

During the 1970s, both the Clark National Forest and Mark Twain National Forest were established. In 1976, the two forests were combined to create what is now known as simply Mark Twain National Forest.

Today the forest is home to over 750 miles (1,200 km) of hiking trails. Many of the trails can also be used for mountain biking and horseback riding. The 350 miles (560 km) of streams in the forest also make rafting, floating, and kayaking popular activities in the region.
