The postindustrial landscape has great potential. The fascination with how to deal with these sites have especially interested land artists. The question of how land art can be used to regenerate postindustrial landscapes, especially in post-mining situations, is a fundamental aspect in this thesis. The thesis attempts to explore the role land art has in this process through an intensive literature research and review of precedent project examples. A concrete example, Martha Schwartzs MacLeod Tailing Reclamation Project in Geraldton, Canada, is examined through a site inventory and spatial perception analysis. Also discussed is how land art developed within the discourse of landscape architecture, how land art through aesthetics challenges our perceptions of postindustrial landscapes, and if land art can be considered sustainable in the context of the postindustrial. Landscape architects and artists are often asked to generate scenarios on what can be done next with these sites. Through land art, the dynamics of human-use versus nature is explored. In the postindustrial, land art can exaggerate the medium of nature, furthering our understanding of what nature actually is. In a society where the dependency on natural resources is staggering, land art can bring to peoples attention cultural phenomenons that are undervalued or exploited, like for example our relationship to nature. Land art is used to develop the aesthetic experiences within a landscape resulting in a new appreciation for the postindustrial landscape. As our perceptions of the postindustrial changes, it influences a transformation in social, cultural, environmental and artistic systems, leading to a new understanding of sustainable thinking. Land art captures the energy and expression of place by questioning the temporal and spatial experiences in landscapes. The MacLeod Tailings Reclamation Project can be an example of a sustainable land art project. The project shows the power of design in remaking a derelict site into a new landscape. More than a beautiful earthwork, the landform is also a cultural artefact highlighting the history and role of mining of the town. Land art challenges our perception of the postindustrial site, transforming into a place of beauty and wonder.
