Denver Colorado USA Vertical Dial 368
On the southwest side of the Emerson School Building (now an office building and historic landmark) is a large white stone vertical dial with a stone gnomon.

The dial was restored when the building was refurbished. See "Sightings" in NASS Compendium Vol. 6 No. 4, Dec 1999.
