Back-scattering w:crepuscular rays. The image was sent to Dr. Andrew T. Young,. Here's his description:

"... it's unusual to see these shadows so clearly at such an oblique geometry: usually, the crepuscular rays are best seen in forward scattering, and much less well in back-scattering. But here, you're looking almost at right angles to the illuminating rays".
