The only thing that I can think of is that memorial day came early this year, with almost a week left in May. Perhaps many of the wildflowers did not begin to bloom until after we left. I did find a couple of wildflowers to photograph. However I have a hard enough time identifying flowers from my area so I am not sure what type of flowers that these are. Perhaps someone from the Wyoming\ Montana area might be able to ID these and let us know what they are.
