After three days full of geysers, hot springs and impressive landscapes, everyone but me wanted to stay home for a day. So I let myself be dropped of at Targhee Pass, at the border of Idaho and Montana. Here I explored a woodland trail for plants such as the Rattlesnake plantain orchid; but the continuous bombardment of images about what to do in case of a bear attack made me slightly nervous in the silent forest. Hence after a while I looked for more open space where I found a variety of butterflies and flies. At the end of the 19th I found a bleeding Aspen tree, a true butterfly magnet. When I came back on the 22nd, the tree had lost nothing about its attractiveness, with three mourning cloaks, various species of comma butterflies and the California tortoiseshell all competing for access to the fermenting juices.
