Starry rosinweed is at Cedar Bog Nature Preserve near Urbana, Ohio. It's a very good example of boreal fen, unusually far south. Cedar Bog has several habitats, all easily visited on trails and boardwalks. It also is a good location for a boreal specimen like me to see a number of species that are rare or unknown at home. It is very much worth a visit.
Cedar Bog is also not too far from Campbell Hill, the highest point in Ohio. Campbell Hill owes its fame to a accident of rising topography as one goes west. It is very little higher than the surrounding area, and very much not worth a visit.
