The paper examines the relationships of deep chemical-weathering to recent landscape development, and the effects of varied lithological and structural controls upon landforms. Relationships between glacial and periglacial processes and forms are discussed, as are reasons for lateral variability in hillside debris movement. Alternative views of the kind of climate associated with the processes are noted and a drier climate is thought to have been more likely than a maritime periglacial climate otherwise proposed. The requirements for any model intended to analyse the history and forms in Falkland landscapes are clarified, and the importance of the history of episodic denudation is stressed.
