Barton County
Barton County, seated at Lamar in southwest Missouri, is a small, lower-source-density rural county whose strongest place-specific topics are durable rather than volatile: the Harry S Truman Birthplace State Historic Site in Lamar; Prairie State Park, Missouri's largest remaining tallgrass prairie with a managed bison herd; a legacy of coal mining on the Cherokee/cherty plains; a row-crop and cattle farm economy; and the long-running Lamar Free Fair.

Bison roam free at Prairie State Park: give them room Prairie State Park has a free-ranging bison herd, so a hike here is not like an ordinary trail.

Prairie State Park protects tallgrass prairie and a bison herd Prairie State Park in Barton County protects Missouri's largest remaining tallgrass prairie and a free-grazing bison herd. Here is what the park is and how to visit it safely. Barton County sits on the prairie plains with a coal-mining past Coal mining is part of Barton County's land-use and economic history, and reclaimed or former mine land can still shape local geology, water, and property questions, so it is worth understanding calmly and from official sources Lamar is the seat, but special districts run many rural services Many rural services in Barton County come from special districts (fire, ambulance, school, road, water) rather than the county or a city, which affects taxes and who to call. Harry S Truman was born in Lamar, and the site is a state historic site The Harry S Truman Birthplace is Barton County's best-known piece of national history and its most significant heritage destination, so getting the basic, durable facts right and pointing visitors to the official manager matters
