Carter was a participant during 1940, in the "Art in Action" exhibitions during the 1939–1940
Golden Gate International Exposition (GGIE) on
Treasure Island. During that time he became a friend of
Diego Rivera, who included Carter three separate times in his mural
Marriage of the Artistic Expression of the North and of the South on this Continent and once in the
Pan American Unity mural. Rivera said the following about Carter: There are three works by Carter on the
City College of San Francisco Ocean Campus,
The Ram (sometimes called the
Mountain Ram),
Goddess of the Forest, and
The Beast. Dudley had donated
The Ram because he knew it was the school mascot and it had been part of the Golden Gate International Exposition's Arts in Action exhibition.
The Ram sculpture stood outside on the campus periodically changing locations from time to time, students would coat it in paint with campus colors red and white. Sometimes rival schools would repaint
The Ram in their own school colors. By 1980,
The Ram had many layers of paint and damage and in spring of 1983 it was restored by Carter with use of a pick axe and its original, natural redwood. Currently located in the lobby of Conlan Hall, on the Ocean Campus.
The Goddess of the Forest is another redwood sculpture created during GGIE. It is very large, standing at 26 feet tall, and had a girth at the base of 21 feet. For years this piece was located at Golden Gate Park, until 1986, when it began to show distress and decay. It was then moved to CCSF, to an indoor location awaiting restoration. ==Clackamas==
