Hiking in Salt Lake and the bad air quality

Amy and I went hiking again yesterday this time in the foothills behind RedButte up to the "livingroom". What I thought was a beautiful sunny blue skies day was really this gross layer of air over the valley that you could chew. It's interesting how hard it is to see sometimes from down below. The second picture is looking at downtown and really, you can't even see it in this picture because of the air. It not the buildings in the foreground, those belong to the campus. Downtown is further out.
