Ozark Highlands: Eureka Springs to Clarksville, AR Professional Review and Guide
"A 95-mile drive beginning at historic Eureka Springs, crossing the Boston Mountains, and ending at Clarksville. The northern part of the drive is in a region underlain by limestones and dolomites. For over hundreds of thousands of years, water seeping into cracks in the bedrock dissolved minerals in the rock, creating caves, sinkholes, and springs. This type of region is named “karst,” after a similar area in the former Yugoslavia near the Adriatic Sea. The Ozarks are one of the best-known of karst regions worldwide, with over 7,000 caves. Leaving the karst region, the highway just beyond Kingston climbs into the Boston Mountains, the highest part of the Ozarks.
Composed of sandstone and shale, this rugged landscape offers great variations in elevation (from 1,500 to 2,300 feet) creating panoramic views and deep, moist valleys rich in wildflowers and crystal-clear streams. Special attractions: Kings River, Eureka Springs, Boxley Valley, Upper Buffalo Wilderness, Buffalo National River, Ozark Highlands Scenic Byway, Ozark Highlands Trail, and Ozark National Forest; fall colors, scenic views, hiking, canoeing, fishing, hunting, and camping."
