Multnomah Falls is the highest year-round waterfall in the United States, tumbling some 620 feet in two stages. I only show a small part of it in this image, honing it down to the great gouts of water that seem to be in the act of diving off the cliff. I also abstract its context, the heavy bank of foliage that embraces the falls. By darkening the foliage, I imply the presence of the trees that frame the falls, but do not show them. The less I show of the vast ribbon of water, the greater the power and beauty of its fall. Such is the power of abstraction as a challenge to the human imagination.
