Recently Siegfried and Gretel Matull returned to their Sea Ranch home via Cazadero. That put them at the top of Fort Ross Road. They were above the fog, looking down. And to their wondering eyes they saw what Siegfried called, "a miracle fog bank" with blue sky above it.
What they were seeing was most likely a partial fog bow, also called a cloud bow, a similar phenomena as a rainbow. A fog bow is usually seen from an airplane. The Matulls were in the right place, at the right time! Thanks to Siegfried for allowing me to share this unusual photo.
