Abstract
The paper presents the view that new instrumentation needs to fuel, but also serve rather than dominate, development of theory in periglacial geomorphology. The variety of periglacial environments, the variable nature of the spatial and temporal signals within periglacial environments, and the scale limitations inherent to instrumental investigations, all combine to focus attention on small‐scale geomorphological investigations. Integration of such findings, that is scale‐linkage, is a difficult, but essential, task that requires development of rigorous theory which is unlikely to be directly informed by the results of instrumental studies alone.
