Another South Dakota picture — this one from a little damp fen tucked away in a much drier Custer State Park:
I have no idea what these little blue flowers are, but each bloom is at best an inch across.
On the way home from our trip to Glacier N.P. and the Canadian Rockies, it so happened that we spent a night in Great Falls, Montana. Before we left the next morning, we stopped off to check out the Lewis & Clark National Historic Trail Interpretive Center — great displays, lots of hands-on stuff for the little one to play with. Oh, and all the landscape plants around the building are historically accurate — just what the Lewis & Clark expedition would have encountered on their way through.
Like these milkweed blossoms.
