Bloomington Indiana USA Horizontal Dial 38
A small horizontal dial, about 18 inches in diameter. The dial plate is tilted 2 deg to the horizon to allow water run-off. However, more unusual is the base that contains a hand crank connected to a scalloped drum that tilts the entire dial to adjust for the Equation of Time. The drum is rotated to the current date and the drum edge pushes a cam that tilts the plane of the horizontal face so that standard time is indicated to within half a minute. The dial is actually mounted on an equatorial axis. Since 1979 the dial has gone into a state of disrepair and is overgrown by bushes. In July 2011 it is reported that the adjusting knob no longer works to tilt the dial.
 
 
Bloomington Indiana USA Horizontal Dial 336
A 24 inch octagonal horizontal dial probably made of marble. The dial is plain, with Roman numerals at the end of hour lines. The gnomon is a simple open triangle of well aged brass. The base is an octagonal pillar surrounded by flowers. The dial was struck by a falling tree in spring 2011. The gnomon style is broken and bent and the support has several large cracks. The falling tree also damaged the surrounding fence.
 
 
Bloomington Indiana USA Vertical Dial 728
An approximately 4 foot square, limestone south-facing vertical dial with a bronze gnomon. Dial face has hour lines and half-hour marks with Arabic numerals. Tall trees shade the dial most of the day.
 
 
Columbus Indiana USA Horizontal Dial 674
A 10 foot diameter horizontal dial of concrete, stainless steel and brick. The gnomon is a massive concrete structure and the Arabic hour markers are inset in the concrete dial face, which serves as a bench.
 
 
Columbus Indiana USA Vertical Dial 675
An approximately 10 x12 foot brick and stainless steel south-facing dial atop a 50 foot tower. This resembles an actual vertical dial but has a horizontal gnomon rather than a polar-pointing gnomon. The hour lines verify against ZW2000 software calculated angles for a due south dial but are non-functional with a horizontal gnomon. Dial face includes hour lines for 6 AM to 2 PM but no numerals. It's more sculpture than sundial.
 
 
Fort Wayne Indiana USA Horizontal Dial 677
A 15 foot diameter stone and cement horizontal dial with a painted steel gnomon. 6 AM to 6 PM hour markers have Arabic numerals. Interior area of dial is filled with crushed rock. A plaque provides EOT and longitude corrections and instructions. This dial was an Eagle Scout project built for this elementary school for use in science lesson plans. Dial sits within a two-course stone perimeter pedestal.
 
 
Indianapolis Indiana USA Equatorial Dial 220
A five foot diameter donut-shaped full circle equatorial pierced by equally massive Indiana Limestone shaft as gnomon. Hour numerals are Arabic. Subdivided into 15 minute increments. EOT is given. Made my David Rogers in 1987 and reported to be Indiana's largest equatorial dial.
 
 
Indianapolis Indiana USA Horizontal Dial 276
A stainless steel and concrete vertical structure 33 feet tall. A stainless steel triangular tube, upright, with triangular and trapezoidal cut-outs, placed in the center of a concrete circle, with a sundial face but may not be functional.
