For 25 years, Physical Geography students of the University of Amsterdam have experienced a 6-week field training in the cuesta landscape in Luxembourg around Diekirch. They studied the geology of the Gutland and surrounding areas, such as Ardennes and Eiffel. They mapped geomorphological patterns, studied soil development and looked at relationships between forest vegetation and the landscape in their particular area of approximately five square km, with many steep slopes. They also learned to overcome the physical and social challenges of such a fieldwork. A number of former students of different generations will give their opinion on what they learned and how this period in life helped them shape their current and future careers.
