Description:
  • The John Myers monumental sundial is truly a masterpiece in time. The 11 foot tall black granite gnomon seems to grow out of a larger granite block. Time is marked by the several rows of low, large flat stones, 25 in all. They are set for summer solstice (first row), equinox (second row that has the stones all in a liner), and winter solstice (only for 10am-2pm. The stones themselves are too large for precise time telling, but the use of colored dots painted on the stones allows you to tell exact civil time using the tip of the sundial's shadow on the solstices and equinox.

    There is a 26th stone "a stone across the walkway under the Hosler Oak. This stone marks the direction of the gnomon's shadow at noon on the solstices as it would have been 65 million years ago..."
