Ronald Blom

Dr. Ron Blom is now semi-retired after 37 years at the Jet Propulsion Laboratory. A career highlight was being one of the co-discoverers of the lost "city" of Ubar, an ancient desert outpost for assembly of camel caravans for transport of frankincense across the Arabian desert. For more information on Ubar, see the PBS/NOVA television documentary "Lost City in Arabia", and read "The Road to Ubar", by Nicholas Clapp, Houghton Mifflin, 1998, 342 pgs.
