Using Geographic Information Systems (GIS) to analyze the dispersion of architectural types within the Willamette Valley revealed trends amongst the extant settlement architecture samples. Brownsville, Oregon, was identified to have a locally-specific architectural subtype, the closer study of which enabled deeper investigation of the development of architectural landscapes during the Willamette Valley's settlement period. Field and archival research revealed that the appearance of an architectural subtype, at least in Brownsville, was not directly connected to a shared provenance of settlers but rather came about through a number of regionally-specific circumstances, especially an active local carpenter community.en-USAll Rights Reserved.BrownsvilleCultural diffusionHistoric preservationOregon TrailSettlementWillamette ValleyElectronic Thesis or Dissertation
