All of the photos get much bigger if you click on them.
A walk through the northern half of the Lower Arb (Carleton College's Cowling Arboretum) this morning revealed a variety of late-summer scenes. In the wooded areas, we were pestered by mosquitoes if we stopped for even a moment or two to listen to a bird or decide which branch in the path to take. In the open prairie areas, butterflies and dragonflies flitted through the tall grasses and wildflowers. In one shaded area we counted a cluster of at least nine monarch butterflies.I love this top photo -- I didn't realize when I took it what an interesting sky there was behind this tall, sturdy, yellow-flowered plant (I'm not sure what it is, but it looks as if it may be in the sunflower family.)
Butterflies seem to love this flower (see also below), which I believe is one of the species of blazing star (Liatris).
A mix of prairie plants. Many of the grasses were taller than me (I'm around 5'2").
Light filtered in a lovely way through a stand of tall, slender trees as we neared the northern end of the Long Loop trail, returning to the small parking area near the old iron bridge on Canada Avenue.
