Wanderlust World Wanderlust World No. Wisconsin lacks major mountain ranges. Its terrain is dominated by rolling hills, glacial plains, and the Driftless Area's rugged valleys. The highest point is Timms Hill (1,951 ft / 595 m) in Price County—hardly a mountain by global standards. The "Baraboo Range" and "Penokee Hills" are ancient, eroded uplands, not true ranges.
