Coeur d'Alene Idaho USA Horizontal Dial Dial 812
In 2013 the city of Coeur d'Alene began a $20M renovation of downtown McEuen Park, a 22-acre expanse, to include a large sundial. But shortly after the renovation started, the city commissioners were told the $51,000 that was to be spent on the sundial was instead to be used to install heavier electrical infrastructure for support of major park events. Fortunately by the end of 2013, the City Staff announced that the sundial was added back to the park's plan, made possible by a $50,000 donation from Parkwood Business Properties.

The analemmal hour lines, equinox and month lines are laser etched into the stainless steel dial plates. The dials and their supporting cradles are 12 gauge with 12" diameters. The post is 1.75" in diameter.

Farmington Utah USA Horizontal Dial Dial 783
A 28 x 20 x 2 inch sandstone horizontal dial with a 1/2-inch thick, hand-tooled copper gnomon. Dial face has Arabic numerals and hour lines corrected for local longitude. Dial was hand carved with carbide chisels and maul but using techniques and natural stone used to create ancient Native American petroglyphs found in the southwest USA. Dial is mounted 2 inches above a sandstone base weighing 400 pounds by brass leveling pins; this mounting makes the dial appear to "float" above the stone base. A "Desert Varnish" finish has been applied to the dial face using a natural process that mimics what naturally happens to exposed sandstone over several thousands of years. The natural color of the stone is exposed by the carving process to create a color contrast as might be seen in a Native American petroglyph. Dial is located in the front yard of a private residence. Viewing can be arranged by contacting the owner by email at theoperativemason@gmail.com

The plaque instruction to stand on the current month is misleading; the user should straddle the dial centerline to avoid an offset error.
