View probably from headwaters of Cerrito Creek, near boundary of modern Kensington, Calif.
A sepia-toned, dome-topped photograph from 1861 captures an expansive, panoramic view of a rural landscape from an elevated perspective. The foreground consists of dark, textured ground covered in dense, low-lying vegetation that slopes downward into a wide, central valley. In the distance, a long, flat-topped ridge sits to the left of a more rounded hill, both rising above a level plain that stretches toward the horizon. The sky is a uniform, pale color with no visible clouds. Below the photograph, a wide strip of aged paper is attached, featuring multiple lines of handwritten cursive text that includes "July 24, 1861," "Rancho San Antonio," "100 ND," and "No. 2245". A small color calibration strip with colored and grayscale squares is positioned at the very bottom edge of the mount.
