2009_ClarkAnalemmicEquatorialThe Portland tour of sundials included Colby Lamb’s Sundial and workshop, a patio sundial of Rob and Julie Brown that also served as a water sprinkler, a vertical mosaic dial at Stephenson Elementary School, the analemmatic sundial at Marylhurst University designed by John Schilke of NASS and Jan Dabrowski, and across the Willamette River to Reed College and a 1912 vertical sundial designed by Dr. F. L. Griffin.  Then more sundials at the National History Site, Fort Vancouver, and ending with the Clark College Equatorial Sundial with a new analemmic gnomon.  Roger Bailey outlined how he helped Soap Lake’s monumental sculpture become a summertime sundial.  Bill Gottesman showed a realization of Fred Sawyer’s Horizontal Equant Dial that adjusts by simple rotation for the Equation of Time.  And most interesting was Silvio Magnani’s presentation on an interactive reflecting heliochronometer in Milan, Italy.  Read about this and much, much more by downloading the PDF.
