Farmington Utah USA Horizontal 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.
