Fog Cascades Over the Hills at Twilight

Fog Cascades Over the Hills at Twilight

Saturday, May 30th, 2026 at 2:27:38 AM · 2026/Mt Diablo Camping - Juniper Canyon

This stunning telephoto photograph captures a dramatic marine layer fog cascade flowing over a ridgeline in the San Francisco Bay Area, likely viewed from Mount Diablo looking toward the coastal hills or Berkeley Hills. The fog behaves like a waterfall, streaming down the hillside in long, silky vertical tendrils — a phenomenon known as a 'fog waterfall' or orographic fog. A flat-topped hill or mountain silhouette rises above the cloud layer in the background, creating a striking layered composition. The sky is bathed in soft pinks and mauves of twilight, and a faint trail of lights — possibly a highway or a string of vehicles — is barely visible at the bottom center of the frame. The image was captured with a long telephoto lens (RF100-500mm) which compresses the layers and enhances the cascading texture of the fog.
