Boston Mountains in the context of Arkansas Valley (ecoregion)

The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, and Oklahoma, as well as a small area in the southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri.

There are two mountain ranges in the Ozarks: the Boston Mountains of Arkansas and Oklahoma, as well as the St. Francois Mountains of Missouri. Wahzhazhe Summit (formerly known as Buffalo Lookout), is the highest point in the Ozarks at 2,561 feet (781 m), and is located in the Boston Mountains, in the westernmost part of Newton County, Arkansas, 6.2 miles (10.0 km) east of Boston, Madison County, Arkansas. Geologically, the area is a broad dome with the exposed core in the ancient St. Francois Mountains. The Ozarks cover nearly 47,000 square miles (120,000 km), making it the most extensive highland region between the Appalachians and Rockies. Together with the Ouachita Mountains, the area is known as the U.S. Interior Highlands.

In the United States, Southern Unionists were white Southerners living in the Confederate States of America and the Southern Border States opposed to secession. Many fought for the Union during the Civil War. These people are also referred to as Southern Loyalists, Union Loyalists, or Lincoln's Loyalists. Pro-Confederates in the South derided them as "Tories" (in reference to the pro-Crown Loyalists of the American Revolution). During Reconstruction, these terms were replaced by "scalawag" (or "scallywag"), which covered all Southern whites who supported the Republican Party.

Tennessee (especially East Tennessee), Kentucky, Maryland, Missouri, Delaware, North Carolina, and Virginia (which included West Virginia at that time) were home to the largest populations of Unionists. Other (primarily Appalachian) areas with significant Unionist influence included North Alabama, North Georgia, Western North Carolina, the Texas Hill Country, northern Loudoun County in Virginia, North Mississippi, North Texas, the Arkansas Ozarks, and the Boston Mountains in Arkansas. These areas provided thousands of volunteers for Union military service. Western North Carolinians, for example, formed their own loyalist infantry, cavalry, and artillery regiments, while West Virginians formed a new Union state admitted in 1863.

Boston is an unincorporated community in the Boston Mountains of southeastern Madison County, Arkansas, United States. The community is located on Arkansas Highway 16 between Pettigrew to the southwest and Red Star to the northeast. The community is on a high ridge at an elevation of 2,329 feet (710 m). The location is at the headwaters of four streams: Kings River to the northeast, War Eagle Creek to the northwest, the White River to the east and southwest and Little Mulberry Creek (a tributary to the Mulberry River) to the southeast.

The Boston Chapel and cemetery lie about three-quarters of a mile to the south of Boston along a county road. The Boston Lookout Tower (35°48′05″N 93°35′59″W / 35.80139°N 93.59972°W / 35.80139; -93.59972 at elevation: 2,454 feet (748 m)) is about two miles south of Boston along the same county road.

Mark Twain National Forest (MTNF) is a U.S. National Forest located in the southern half of Missouri, composed of nine disconnected parcels. MTNF was established on September 11, 1939. It is named for author Mark Twain, a Missouri native. The MTNF covers 3,068,800 acres (4,795 sq mi) of which 1,506,100 acres (2,353.3 sq mi) is public owned, 78,000 acres (122 sq mi) of which are Wilderness, and National Scenic River area. MTNF spans 29 counties and represents 11% of all forested land in Missouri. MTNF's nine tracts are divided into six distinct ranger districts: Ava-Cassville-Willow Springs, Eleven Point, Houston-Rolla, Cedar Creek, Poplar Bluff, Potosi-Fredericktown, and the Salem. Its headquarters are in Rolla, Missouri.

Some unique features of the Mark Twain include Greer Spring, which is the largest spring on National Forest land and part of the Eleven Point National Scenic River with an average daily flow of 214 million U.S. gallons (810 million liters). The public can also visit the Glade Top Trail National Scenic Byway, which offers views of over 30 miles (48 km) to the Boston Mountains in Arkansas. The 350-mile (560 km) Ozark Trail system winds through much of the National Forest.
