Santa Cruz Island California USA Vertical Dial 899
This vertical dial has undergone a number of restorations since it was set in lime in 1889. A photograph from 1900 shows the placement of a gnomon rod is horizontal. In 1992 before the National Park Service restoration in 2012 the gnomon is set in a polar orientation. But it doesn't really matter since the hour lines are marked at nearly regular 15 degree intervals with half hour sub-marks.
