The third rapids & more lichens

Filed under: Lichens, Winter — Tags: , , , — montucky @ 10:11 pm

On the Clark Fork River, a half mile down stream from where I live there are two sets of rapids visible from the highway, much admired and often fished and photographed. A mile down stream from them is a third set of rapids but not visible and hardly known, but it can be reached by a mile hike through a section of state land from the far side of the river. I enjoy fishing there and visit at other times of the year also to enjoy the scenery and wildlife.

Today the temperature was about 20ºF and an icy breeze was blowing down river, but the sky was clear and it was pretty down at the third rapids

but what I found most interesting was the variety of lichens ( most of which I could not identify) growing on some exposed rocks and trees.

In today’s steady rain, a couple of miles up Buffalo Bill Creek, the only “sunshine” I saw was this brightly colored lichen. Its yellow color is derived from two poisonous substances, pinastric and vulpinic acids which occur only in lichens and are thought to deter grazing by insects and other invertebrates. Pretty, isn’t it!
