A small cross-bar in the middle of the gnomon acts as a nodus for telling the date. A mechanical adjustment allows for the equation of time correction. The dial is mounted on a large boulder on the Northwest end of the Goldendale Observatory close to the Solar Telescope Building.

Hour lines have inset disks to indicate the hour, one disk for each counted hour 6 AM to 7 PM. The mid-day N-S hour line features thirteen hour disks; the previous hour has 12 disks and the next hour is marked with two disks.

Seattle Washington USA Vertical Dial 744
A 10 x 18 foot vertical dial on a south-facing brick wall. The hour lines are stainless steel sheet and are formed to create shadow effects that change with the position of the sun. The stainless steel Arabic hour numerals are on disks that are held on the wall by magnets, allowing them to be placed for ST or DST. A stylized school emblem is placed at the base of the gnomon.

The hour lines are aluminum strips terminating in Arabic hour numerals. The dial face includes ceramic disks painted by school students and are placed so that the gnomon shadow falls on then on their birthday.
Seattle Washington USA Cylinder Dial 746
A unique, 10 foot tall, 2 foot diameter (base) tapered cylinder dial similar to a traditional shepherd's dial except that the cylinder orientation is fixed and the gnomon is rotated about the dial axis by the user to align with the sun. Time is read from the vertical hour and date lines. The dial is fabricated from bronze plate and is hollow. Lines are formed by individually cut hour and date line segments welded on from inside the cylinder. A lever at hand height is moved to rotate the gnomon to face the sun, providing a vertical shadow. A slit in the gnomon tip provides a more accurate sun spot on the dial face. The cylinder is tapered top to bottom for aesthetics and to minimize the effect of solar altitude variation through the seasons. Ray Monnat, father of two students at the school was the dial project leader, organizing and funding the project. Woody Sullivan, Professor of Astronomy at University of Washington was the designer, assisted by Art Teacher Peggy Dow; Larry Stark designed the turning mechanism. A plaque on the dial base shows the EOT and provides information on the dial. A depiction of the school mascot, a puma, is engraved on the rear of the dial, shown leaping through the orbit of Halley's Comet.
