The Making of Amarillo Ramp  documents the construction of Robert Smithson's earthwork Amarillo Ramp.  At age thirty-five, while photographing  the site of the earthwork in progress, Smithson died in a small airplane accident, along with pilot Gale Ray Rogers and photographer Robert E. Curtin. After Smithson's passing, Nancy Holt, Richard Serra, and Tony Shafrazi completed Amarillo Ramp according to Smithson's specifications. This film documents the sounds and actions of the powerful machinery necessary to create an earthwork of this scale, while underscoring the human skill and personal relationships that were integral to the completion of the work.
