On the 40th anniversary of the dedication of the Buffalo River as America's first national river, this special edition of Exploring Arkansas will take you on a john-boat float trip down the middle portion of the river where two unique rock formations can be explored -- the "Nars"and Skull Bluff. Program concludes with a hike along one of Arkansas's premier hiking trails -- the Goat Trail which meanders along 500 foot-tall Big Bluff in the Buffalo's upper portion.
