Mystical Mists of the Foothills: Captured by Michael Frye Photography

The Central Valley of California is frequently enveloped in fog during winter. Typically, a thin layer of fog develops overnight, only to dissipate the following morning as the sun heats the air. During the night and early morning, there exists a temporary, shallow inversion where the air near the ground is cooler than that aloft; however, once the sunlight penetrates the fog and warms the land, the inversion ceases.

Occasionally, though, the fog in the Central Valley becomes so dense that it doesn’t clear. The feeble sunlight of short winter days fails to completely penetrate the fog layer, resulting in fog lingering all day, extending into the following night. If the fog endures for several days, the inversion can grow deeper (reaching up to two or three thousand feet), and the fog gradually lifts off the ground into a low overcast, or stratus deck. This elevated fog layer may then ascend into the Sierra foothills. Such stratus decks can linger for multiple days, or even up to a week, until a disturbance in the atmospheric conditions (like a storm, or even a mild, dry front) stirs the air and eliminates the inversion.

This phenomenon might take place two or three times each winter. Whenever it does, I will seek out viewpoints in the foothills above the fog layer, allowing me to gaze over the cloud sea.

Finding the ideal perspective isn’t straightforward. There is limited public land within the Sierra foothills, which means one is usually confined to capturing images from public roads. Additionally, the fog level must be just right. I ideally hope to find a viewpoint that’s just above the fog layer. If the fog is too elevated, you are engulfed in it, viewing a dense soup. If it’s too low, you may not see it at all, or only in the distance. Naturally, the fog layer fluctuates, making it challenging to forecast.

I have made it a priority to traverse all the backroads in the foothills within an hour’s drive from my residence, so I am familiar with all potential vantage points. This is something I would advise any landscape photographer to do – familiarize yourself with your local area and identify all the intriguing locations with photographic promise, so you can swiftly get to the right spot if conditions appear favorable.

This local awareness proved useful this past week when a profound inversion and accompanying stratus deck stuck around for several days, pushing fog into the foothills. Claudia and I discovered viewpoints above the fog Wednesday morning, Wednesday evening, and Thursday morning, and we thoroughly enjoyed ourselves. I have included some of my still images here, along with Claudia’s time-lapse video.

There is something truly enchanting about standing on a hillside above the clouds. You feel as if you are in a different realm, bathed in sunlight, floating above the dreary preoccupations of the shadowy world below. It’s genuinely magical, and I hope we get the opportunity to experience it again this winter.
