Pestle Stone Sunset

Summer hiking in nearby Colton’s Stone Valley is rapidly approaching, and with it, opportunities to see some of our odd (to me) local geology. Those enormous hollows are created by the movement of trapped pestle stones in the rapids water; the scattered evening light reveals their depths.

End of the Blue Hour: San Francisco

A history of design and engineering is visible from the Marin Headlands in the Golden Gate Bridge and San Francisco beyond it. That’s visible at every hour of the day, so I must conclude that the people jamming the roads earlier on the evening of this image were mostly there for the combination effect with the sunset. As the crowds decamped for dinner elsewhere, the blue hour brought my favorite views of the city.
