Query: from Chapter 15

"The wave, ruler edge in the bright winter dawn, feathered ahead as I flew; cold, wet speed as the lip thinned to ten yards of spray, ready to break. Two toes off the tip trimming toward that shaking fringe, then carving high and, just as the whole wave lept forward, soaring along the breaking back. And, in that intant's tableau -- a telescopic view down a glimmering glass wall below a snocapped green mountain and a morning rainow -- I became airborne just as a truly enormous dolphin (perhaps nine feet long) exploded from the wave ahead, its shining gray body for a moment in flight. We both hung in the rising sun long enough for me to shout out loud in astonishment and lose all balance, tumble into the foam as the dolphin speared the surface and vanished. I bobbed about on my back, stared at the dark blue sky and tried to think of a God to whom I could give thanks."
