In the 1970s, Marsh collaborated with the art group Ant Farm to create the Cadillac Ranch. Marsh has funded other public art projects in Amarillo besides Cadillac Ranch, which include the "Dynamite Museum," an ongoing project consisting of hundreds of mock traffic signs. These signs, bearing messages such as "Road does not end," "Lubbock is a grease spot," and "I have traveled a great deal in Amarillo," may be found throughout the city of Amarillo. A series of the mock traffic signs are also displayed in Adrian, Texas, about 45 miles west of Amarillo. Marsh was said to have wanted the signs to be placed in towns beginning with the letter "A". Additional public art projects sponsored by Marsh were a supposed remains of a giant statue called "Ozymandias" and the "Floating Mesa," a huge natural mesa with a narrow white band wrapped on top of it.
