We walked through a misty eucalyptus forest near the San Francisco Bay at Point Pinole Regional Park yesterday until we made it to the shoreline. At high tide, the sun shown onto the fog and a perfectly white semicircle arched before us over the gentle bay.

Known as a white rainbow, or fog bow, this beautiful sight is one totally unfamiliar to me despite all of my professional career studying fog. It lasted for at least 10 minutes, hanging before our eyes and providing an excellent backdrop for shenanigans like family selfies. 

We almost didn’t walk at Point Pinole yesterday because it seemed so drenched in fog while the rest of the east bay had sun. Luckily for us we ventured through the fog anyway. 🌈
