Over this past week I have gone to Cholla Power Plant, Fort Valley Experimental Forest, and the Grand Canyon.  I have learned that there is a haze over the Grand Canyon.  That haze covers the beautiful color of the Grand Canyon. 
                My grandmother told my that when she was my age she could see Navajo Mountain very clearly, but now all you can see is the silhouette of the mountain. Also back then you could see 80 or 90 miles, now you are lucky if you can see 30 or 40 miles.
