Mt Thielsen in the OR Cascades. One of the more dramatic mountains in OR so far. As you can see it is a blue bird day at the time of this photograph. The trail winds around Thielsen to a small creek that was still running due to the excessive snowfall OR received this winter and as soon as we reached the creak the entire peak disappeared behind clouds and fog and the temperature dropped 20° in a matter of minutes. I have not seen a change in the weather like that since the Sierras and we were just below 7500 feet.
