Salt Lake Valley from Little Cottonwood Canyon

One thing that stands out from any view of the Salt Lake Valley is the pollution in the air and this was a relatively clear day. Both Little Cottonwood (the big canyon) and Big Cottonwood (the narrower canyon) are high enough at the top to be out of most of the stuff in the valley air. But as you come down the canyons you are always reminded of the smog or smust, or whatever is in the air.
