Directly intervening into nature, Long’s intent is documented as one that originated from seeking to make nature the medium of the artwork. “Nature has always been recorded by artists, from prehistoric cave paintings to twentieth-century landscape photography. I, too wanted to make nature the subject of my work, but in new ways. I started working outside using natural materials like grass and water, and this evolved into the idea of making a sculpture by walking”.
While artists such as Long oriented themselves similarly to the Arte Povera artists, working with “poor”, or natural materials, some Land Art employ machinery in large-scale efforts to create monumental excavations and constructions. Most prominently working on this scale is artist Michael Heizer who has been working since the 1960s.
