  • Lawrence Hall of Science at the top of the hill on UC Berkeley campus
  • This is a large granite statue by Richard O'hanlon entitled "Sunstone II" and was designed in collaboration with astronomer David Cudaback. A north-south large polished granite slab has the top cut at the latitude of 38 degrees to sight the North Star. A hole in the stone allows east or west viewing, with limiting angles designed to show the extent of maximum planetary and lunar wandering. An east-west stone crosses the north side of the granite slab, allowing light to pass only at noontime onto a heel stone with marks for Equinox and Solstice. Access by admission to the Hall of Science museum
