To get the boulder field to fill a higher percentage of your frame, shoot from a high position. When shooting from a higher position, the foreground rocks are not emphasized in size relative to the more-distant rocks.
Once again, I was dealing with clear sky. In this case, I chose to only show enough to give the frame a clean blue border.
