Missouri’s only national forest, the Mark Twain, encompasses roughly 1.5 million acres, mostly within the Ozark Highlands. Located across southern Missouri and northern Arkansas, the Ozark Highlands are an ancient landscape characterized by large permanent springs, over 5,000 caves, rocky barren glades, old volcanic mountains and nationally recognized streams. Portions of the Ozarks were never under oceans, nor were the areas glaciated. MORE
