Marquette County holds some of Upper Peninsula's wildest lands and most scenic waterfalls. Parallel to the Lake Superior shoreline, sweeping north from Marquette, are the Huron Mountains, giving rivers and creeks flowing from the Yellow Dog Plains and Pesheekee Highlands a barrier that they must wind through and drop over. In the south end of the county, the heart of the area's iron industry, large rivers flowing south to Lake Michigan must travel over jagged, fragmented bedrock between small, stinking swamps.
