I have had dandelion tea and it is wonderful. There is also an oak grove, burr oak (Quercus macrocarpa) or swamp white oak (Quercus bicolor) I dont recall now, adjacent (north side) to the portage between Saganaga and Swamp. Native or not native that is the question... The same types of plantings exist in the WCPP also and include even an American Elm on telescope lake, I recall the oaks in that neck of the woods being further north though...agriculture!
