John Steiner, the blogger behind Journeys With Johnbo, has this prompt he calls Cellpic Sunday in which he asks us to post a photo that was taken with a cellphone, tablet, or another mobile device. He invites us to participate in this cellphone photo prompt by creating our own CellPic Sunday post and linking it back to his.

The photo I’m featuring today is one I took 11 years ago yesterday, on December 2, 2012 with my new (at the time) iPhone 5.

This photo shows Rainbow Falls in Golden Gate Park. It’s a manmade structure that was constructed in 1929 to create a recycling waterfall over what was a rock quarry where the stone was used to pave the roads in the park. The waterfall cascades water down more than 50 feet in two leaps into the former quarry.

If you look carefully behind the top of the waterfall, you can see a giant cross, the Prayer Book Cross, sometimes called the Sir Francis Drake Cross. It is a large stone Celtic cross sculpture that was dedicated in 1894. The monument is constructed on a pedestal of stone eighteen feet square and seven feet height. The Cross, itself, is 57 feet high. It commemorated Francis Drake’s landing in New Albion at nearby Drakes Bay and the first use of the Book of Common Prayer in what would become the United States.

The photo below is not my photo. It came from ArtandArchitecture-SF.com. I’m including it so you can see what is atop the waterfall.
