The earth’s rotation has a wobble to it which causes the exact spot on the earth’s surface to vary through the millenniums. Thus, the timing of the Sun Dial varies from today to yesteryear (Hranicky 1987 and 1988).

As a boulder set, the sun dial boulders A, B, and C are on the same horizontal area as boulder D which is below them. Both groups are square with the linear north/south vertical sides. Boulder D is longer on the northern end. The boulders B and C are shimmied to level them. Their configuration is shown.

Spout Run Ceremonial Site

Class: Petroglyphic

Time: Unknown

​Location: Clarke County, Virginia


The Spout Run site in Clarke County has a Sun Dial which was used for annual religious practices, such as solstice-to-solstice, and the sun’s daily movements, such as high noon. The year was probably sun’s east-west complete trip across the sky. The day was probably from high noon to the next day’s high noon. The time periods are suggested but not proven.


The Sun Dial has three boulders setting on top of a large boulder which is directly east from the observatory ring and, collectively, they are classified here as the Sun Dial. The upper boulders were placed on top of a large boulder (not geological actions). Figure shows the set, and they are approximately 400 yards from the main site. The dial has two channels; one is oriented north-south and one channel facing east. They have solar positional aspects to time. In order to level the top boulders, they were shimmied. The levelness is off only 3 degrees.


The boulders are a set-up construction:
• East-to-West channel for daily sun movement
• North-to-South channel for annual sun movement.
