The Northern BC Archives has extensive collections on northern expeditions and surveys from 1907 to the 1930s. Most of these collections largely consist of photographs with some textual records and maps. 

Research Significance: Many of these collections such as the Prentiss Gray Collection and the Phipps-Mackenzie Collection provide visual documentation of natural landscapes of Northern BC and Alberta including flora and fauna. Such photographs and cartographic materials may generate and provide opportunities for comparative analyses of previous landscape conditions with contemporary environments, creating a benchmark for documenting natural habitat and changing environments or industry practices.
