The two pictures above show the Hyderabad Obelisk before it was shipped to Sristek company for its corporate headquarters lobby. The sculptor's mother, Rosamond Sievers, is pictured when it was located in the Avalon Ballroom. This marble piece has very pronounced gradation of coloration from green and white to rose and black regions caused by differences in metal ions that are pigments and possibly by differences in oxidation states.
The National Oceanic and Atmospheric Administration, NOAA, requested that Sievers carve this sculpture for permanent installation in their entrance lobby, which faces the Flatirons Mountains west of Boulder. This was stimulated by the sculptor's role as director of the Cooperative Institute for Research in Environmental Sciences, CIRES, a joint institute of NOAA and CU from 1980 until 1993.
