Shooting distant landscapes, especially in the Grand Canyon, often involves air clarity issues. Plan on adding a lot of contrast to your images to counter these conditions. Shooting early in the day often helps.
Another challenge visible in this photo is the flat plateau. Like water, this flat surface is unforgiving to a non-level camera - and illuminates lens distortion. Lens distortion also makes it hard to level the camera in the first place.
This picture was taken near Yavapai Point. Note the late May snow in the background.
