Here is the epitome of an Arizona sunset: it really puts the Arizona state flag into perspective. The patch of clouds casting beams of shadows (or the sun casting beams of light, depending on how full your glass is).
As you may have seen in the Virga post, drops of rain from a storm at sunset catch the red light as they try to reach the ground.
Although the sun is a little too high in this shot to give us the epic sunset clouds over the lake, I really like the cooler colors during this Monsoon-season frame and the contrast of the dark clouds overhead. By the time the sun came down enough to begin to light the clouds over the lake it became obscured and the show was over.
