Iain,
 
Actually, you may extend the geographers germane to historical archaeological research back several more decades.  Although folklife researchers have used British geographer E. Estyn Evans' work since the 1960s, few archaeologists have bothered to read/cite his work in North American studies.  They almost without failing flock toward the trajectories of thought inspired by Fred Kniffen, which were adapted (along with evans' work) by Henry Glassie in his somehwat uneven studies of American material culture, mostly architecture.
 
To get more of a feel for what geographers have to offer the study of material culture and how the work of geographers has been used, your best bet is to turn toward the folklore studies in Great Britain and to folklife studies (also, in Ireland, but mainly in the Scandinavian countries).
