Captured with Rodenstock 138mm/6.5 HR Digaron-SW lens (@ f/7.1), Phase One IQ4-150 back (@ ISO 50, 1/100 sec), Cambo WRS 5005 camera, stitched panorama of two images, shifted left and right +/- about 20mm.This seemingly endless section of the Hetch Hetchey aqueduct travels above ground for a stretch, after crossing the San Francisco Bay. It seems endless. An abandoned stretch of the former Southern Pacific Railroad is visible in background.Infrastructure is heroic.

    California's Hetch Hetchy aqueduct, completed in 1936, supplies about 85% of the water used in the San Francisco Bay area. Originating over 160 miles away, at Yosemite's Hetch Hetchy reservoir, and working chiefly by gravity, a 21 mile section of two pipelines crosses the South Bay via a series of above- and under- ground tunnels and bridges just south of the Dumbarton Bridge. This section, near the end of its useful life, has recently been augmented by a deep tunnel.
