Surveying the Leisure Wastelands is a project by casati (Simon Oberhammer, Alexander Pfanzelt), which was realized in the context of ART in Public Space Tyrol in winter 2010/11. For over a year, casati followed the traces of abandoned leisure facilities and ski lifts and presented the results of this artistic research on changes in the landscape due to the changing demands of leisure time activity over time. The development of leisure wastelands following the closure of lift systems is a process that can be observed now for approximately 15 years. It did not begin in remote valleys but in heavily frequented places at a height of more than 1,100 metres above sea level, like the Brenner, Scharnitz or the Fernpass region. In this project casati use the remaining traces as a medium. They can be used as symbols, if they are recorded in their original form as patterns located on a slope, and make the disappeared, invisible image of the leisure wastes visible again in a different place. Besides two installations in public space in Heiterwang and Scharnitz, a guide was also issued to document the leisure wastes researched.
