Yesterday we went a little bit upstream of "my" lake to do some bacterial habitat sampling. Check out the looming storm- it was right on top of us just a few minutes after I took this picture. There's nothing like being in the middle of nowhere with thunder and lightning! It passed over us quickly though, and those of us who thought to bring rain suits stayed fairly dry.
Last night I presented some of my research to camp and was followed by a Canadian grad student who does terrestrial microbial work. Now I'll be able to go back and fill in the proper names to some of the flowers I've been photographing all summer. This one is a yellow arnica, Arnica angustifolia.
