Portland and Vancouver occupy the heart of this survey, which documents the industrial and urban expansion along the Willamette River and Columbia River before the heavy modifications of the mid-20th century. Notable landmarks include the Vancouver Barracks and the sprawling Asylum grounds, while the presence of Columbia University and University Park points to the early educational development of the peninsula. The river landscape is characterized by numerous islands and sloughs, many of which were still in a natural state or being adapted for early aviation at the Port of Portland Airport on Swan Island.
