Deadline Falls, Oregon, is the largest of several small cascades where the North Umpqua River cascades over and through small outcrops of basalt riverbed. The falls are not the most impressive waterfall in the region, and wouldn't usually be an attraction in this neck of the woods, except for the high likelihood of seeing large Salmon leaping the falls as they migrate upstream. From May to October you'll most likely see fish jumping and splashing around in the pools below the falls.
