We found this sedge (note the triangular leaves - an important clue that it is a sedge and not a rush or a grass) down at the Ice Meadows.
It was such a lovely thing that I had to take its photo.
Up close it is even more intricate than one could imagine.
I'm leaning toward it being some kind of bulrush (which are in the sedge family), but my books are just not detailed enough. For all I know, it could be a Cladium (Cyperaceae).
